Missed Miscarriage or Misdiagnosis? No Heartbeat at 10 Weeks 136


I was told at 10 weeks that my baby had no heartbeat and had stopped growing at 8 weeks. It was just a routine dating ultrasound. I’d had no bleeding, no cramping, and no indication that anything was wrong. I suffered from a missed miscarriage. As a mother of three healthy boys with no previous history of miscarriage, this was a new experience for me and one I found would have been far easier on me had I known what to expect. I’ve chosen to share my story from start to finish in a series of short articles so that other women who face what our family did are more prepared. You’ll find my story enhanced with research as well as information gleaned from talking to other women who have had miscarriages and healthcare professionals I met through the process to help answer questions you may find yourself asking. missed miscarriage

Article one will deal with whether or not missed miscarriages or miscarriages in general can be misdiagnosed, whether or not you should get a second opinion, and if so, when.

When I was first told I’d had a missed miscarriage, the doctor was very brusque. The ultrasound was very short and my options were shorter. I could have a D&C (Dilation and Curettage) or wait it out naturally. I didn’t believe him. I left that office 100 percent sure he was an incompetent hack. I spent the next week reading stories of people that were told they’d had a missed miscarriage and had everything turn out OK. One minute I was sure my baby was fine, the next I was in tears because I knew she/he wasn’t. It was the longest week of my life.

Is it possible for a miscarriage or missed miscarriage misdiagnosis to happen?

Yes, based on forum responses from women on misdiagnosedmiscarriage.com and personal interviews with women who preferred to remain anonymous, misdiagnosed miscarriages are most common in early pregnancy.

Your chances of a missed miscarriage misdiagnosis may be higher if:

-You are 6 weeks pregnant or less. The further along you are after the 6 week point, the lower the chance of miscarriage misdiagnosis.

-Your ultrasound was not done vaginally. Vaginal ultrasounds are far more accurate in early pregnancy.

-A fetal pole was not seen. This may indicate your due dates are off or you may have a tilted uterus. It appeared to be more common for no fetal pole to be seen and a baby to be found later, than a baby with no heartbeat to later have one.

If a baby is seen measuring 8 weeks or larger with no heartbeat, the chances are quite slim that you had a misdiagnosed miscarriage. If you’re looking for hope, I know that’s not what you want to hear, but I found false hope made my week of waiting far longer. In my case, I was wrong, my doctor was right, and I did have a missed miscarriage, but I’m still glad I got a second opinion. Most of the women I spoke to felt better about things if they got a second opinion or wished they had if they didn’t. It offers that certainty that keeps you from wondering if you’re doing the right thing if you opt for a D&C or struggling with the idea your baby may be alive if you decide to wait it out for a natural loss.

How long should I wait before I get a second opinion about a missed miscarriage?

I know your first instinct is to run straight to another doctor, clinic or the ER to get a second opinion right now, but the general guideline is to wait at least one week. If you get a second opinion right away, yes you’re getting a new machine and new person reading that machine, but if your due date is incorrect or your baby is developing slowly due to other circumstances, it’s possible you’ll still get a misdiagnosis. Many women who get ultrasounds around 6 weeks find no heartbeat and later find one. Your baby’s heart begins to beat around 6 weeks. If your due date is even a few days off, you could be misdiagnosed with a missed miscarriage.

What about HCG blood levels to catch a missed miscarriage misdiagnosis?

I declined HCG blood testing for the most part. I didn’t want one more thing to stress over. Why? HCG is supposed to double every 48 hours in early pregnancy before peaking around week 10 and then it begins to decline. Note the word, “supposed.” It is not uncommon for women to have non-doubling HCG levels and have perfectly healthy pregnancies. If your due date is off, your levels could already be dropping. If your baby passed recently, your levels may not have begun to drop off and could remain high for weeks. There are so many things that make HCG levels irrelevant; it’s really just information that’s going to make you worry more. What you do need to know is that your levels return to zero if you do indeed miscarry, meaning a blood test after your loss, if it happens, is recommended.

Article two covers handling the grief of a miscarriage. I hope that this article helps those who are facing a possible missed miscarriage and a sincerely hope you have no need to read article two.

    I still don’t understand, I had no spotting, no cramps, no signs of any sorts as read. My first u/s read I was at 8 weeks 2 days, no heartbeat. So I was sent to 2 blood tests 5 days apart & my HCG was increasing positively which made my GP send me to the second U/S 9 days after. This time they did the vaginal one as well and unfortunately still no heartbeats. I can’t wait to see my GP tomorrow as the last 2 weeks was just a nightmare to me. What is going on? I have 2 healthy boys and never ever experienced any miscarriage before. This is really frustrating!:(

      Unfortunately, HCG can sometimes continue to rise for a short time even after a missed loss. 🙁 If you’ve had two scans 9 days apart, a misdiagnosis is a lot less likely, I know that’s not what you want to hear, and I truly do hope that I’m wrong and you’re one of those rare few, but I’m sorry for your loss if not. I had 3 healthy pregnancies prior to 3 losses in a row. It is very frustrating and confusing, but it happens, and sometimes you never find out why (I didn’t).

    Okay I’m doing my best to stay positive here, so yday around 10.15am I had contraction like pains, it didn’t subside after 10 mins so I rang 111 and before I could finish I started to bleed. I was told to get to the hospital within the hour which I did. I had blood tests and a pee test and they all come back fine. I couldn’t have the scan till today. I was sent home told to worry and rest. I didn’t bleed through the night or anything so I was becoming more positive as I hadn’t lost to much blood, despite it being bright tedit was very watery. When I woke up and showered this morning there was some thick brown blood. I tried my best to put my worries aside and get to the scan. I had my scan at 11am I saw the baby’s heartbeat and my cervix was closed. All good news they said. The bleeding and pain wasn’t an issue so I was sent home. When I got home I was fine for a few hours I got really bad cramping while cleaning so I stopped and rested. I went to the toilet an hour ago and my wee in the toilet bowl was that bright red watery colour. No wee to be seen just red. I rang the hospital and said what had happened and they don’t seem to really care or seem to be concerned coz the baby and my cervix was fine earlier. Anyone have anything similar? This little buba is a trouble maker 7 weeks in and I’ve had two scans and faint bleeding. I haven’t passed any clots or any thick blood but I am worried.

      Unfortunately, checking for a heart beat and to ensure your cervix is closed is all they can do, if it is a loss and there’s no visible sign of something they can fix, wait and see is all that’s left. That you saw a heart beat is a very good sign though. 1 in 4 women have early pregnancy bleeding and many of them go on to have healthy babies. I hope things calm down for you any everything goes smoothly from here on out.

        I’ve been back for a further vaginal examination to see if there is any trauma to my cervix etc but they couldn’t find anything untoward and said I’m still closed which is a good sign. I’ve still got the brown blood everyday but hopefully in the next two weeks or so I get the 12 week scan. Fingers crossed I see my baby alive and not be told the daunting news like the last 12 week scan. I’ll be 11 weeks this coming Thursday

    I am having such a hard time dealing with this ! It’s comforting to read your article, since I too was told that I had a misses miscarriage and have truly been struggling with accepting it. I have experience two months of bleeding and/or brown .. blood or discharge – I am really unsure. I keep finding myself holding on to false help, and I never went back to the doctor out of frustration. I just knew that I was further along than what the doctor had told me, and based on my last period I should have been. I did lose the pain in my breasts, but I still feel as though my stomach is larger than normal, and lack of eating still affects me the same way it did when I was pregnant. I never received an expected date of delivery because the sonographer could not see anything. I should have been 9 weeks based on my last period. By my last visit, the sonographer apparently noted that she did not find a heartbeat but that the sac measured to be about 6 weeks. I have literally been struggling as I have 3 friends that are currently pregnant and will be expecting around the time that I was due. I just want to know if there is any hope – any way to figure out how to get my body back to normal. I am almost desperate to hear a story of the same situation, that turned out to be a healthy baby. Maybe I should go ahead and read article 3. Do I really need a doctor or does this process truly just take more than two months ?

      If your bleeding has continued over several months and you haven’t seen any tissue, I would go see a care provider, hope or no hope. With a first trimester loss, you wouldn’t expect this level of prolonged bleeding. It’s possible it’s just a lingering hormonal imbalance or your loss is just taking a long time (I did have spotting for about a week before one of my full losses), but it’s worth being sure. It would also offer you some closure (or confirmation that your hope was valid, as bleeding in pregnancy can happen).

        I think you’re right. I can’t continue to allow my pain and frustration to cause me to think and act without logic. It’s best that i go ahead and get checked out to know for sure that things are ok. Here and there i do see some sort of clot or tissue come out but not regularly. Thank you for sharing your story and giving advice on a difficult situation that you too have had to go through. Thank you for this – for helping me deal with my loss and I’m sorry that you’ve had to experience this on more than one occasion. It is very hard ! Thanks again !
