Missed Period, Negative Pregnancy Test? Causes Other Than Pregnancy 46


Missed period? Negative pregnancy test? Yeah, that can be pretty confusing—mostly because basic health class failed us all. It may be common knowledge that pregnancy can cause a missed period or periods, but there are other lesser known causes as well. You can miss a period without being pregnant. So, assuming you have the missed period negative pregnancy test situation, what else could it be?missed period negative pregnancy test

It was a false negative pregnancy test.

You can read about the possible failure of pregnancy tests in-depth here, but basically, home tests are not error proof. You could have tested too early, gotten an expired test, misread your result, or even be one of those women that just never get a positive home test (I have known a few and their children).

Now a blood test is far more definitive. Excluding lab error,  false negative blood tests don’t happen. If you have a missed period and a negative pregnancy test along with pregnancy symptoms, most doctors will still just do a urine test unless you’ve missed more than one period. So, to save you some cash, it’s recommend you forgo alcohol and other not-pregnancy-safe stuff, and wait to see what happens when your next period is due. 90 percent of the time women who have the missed period negative pregnancy situation end up getting their period—just a bit late. If you miss another period, you might speak with a care provider for a blood test. It should also be noted, it is possible to have bleeding and be pregnant, you can read about that here.

You have some level of hormonal imbalance.

OK, with that out of the way, what are those other causes of a missed period with a negative test? Several hormonal imbalances can mimic pregnancy, the most common of which being high progesterone.

Progesterone is a hormone that maintains your uterine lining during pregnancy. Its rise is triggered by ovulation, and it remains high until either the egg begins to die, so to speak, or you become pregnant. If you become pregnant, implantation signals progesterone secretion to continue and increase. If you don’t become pregnant, once levels drop low enough, you’ll get a period. It’s the high levels of progesterone in early pregnancy that cause many  common pregnancy symptoms including sore breasts, gas, bloating, and even nausea. This is why some women experience some or all of these issues as PMS. If you have a high-progesterone cycle (levels naturally can vary by cycle), you may have a longer than usual cycle (late) along with pregnancy-like symptoms.

Low estrogen can also have this effect as it delays ovulation. When you ovulate late, the second phase of your cycle dominated by progesterone remains the same length in most cases. This makes for a longer cycle as well. Low estrogen is less likely to cause pregnancy-like symptoms, but you may experience vaginal dryness, painful intercourse, and dry skin.

You can learn more about other signs of hormonal imbalance that can affect your cycle in situations such as short periods, irregular bleeding, and spotting here. If you experience more than one cycle indicative of hormonal imbalance, you might try Vitex, a slow-acting herb often effective in hormone balancing. If you aren’t trying to conceive, birth control is also commonly prescribed.

You didn’t ovulate.

Next, if you fail to ovulate, you may experience repeated seemingly missed periods. You can think of your menstrual cycle as being like dominoes. Each phase triggers the next by altering your hormone balance. Ovulation is the key piece to switching from high estrogen to build the uterine lining and high progesterone to maintain it. If you don’t ovulate for one reason or another nothing prompts progesterone to rise. Depending on your natural hormone balance, estrogen may just continue to build your lining for some time, and you won’t get a period. Some women also experience frequent or irregular periods when not ovulating, but excessively long cycles that appear to be missed periods are more common. Note that these periods are not technically missed, they simply haven’t started yet. Many women will eventually ovulate during a super-long cycle, and either this, or an inability of estrogen to keep the lining up, leads to bleeding.

Failure to ovulate often has an underlying health cause such as ovarian cysts or low egg reserve. You can read more about the causes and risk factors for anovulatory cycles here. The exclusion to this is while breastfeeding, when wonky or absent periods are expected.

I’m unsure of my period in July as I’m irregular and was on the pill through July 10th. I forgot to renew them so I didnt restart until 8/19 as I was “bleeding” it wasnt a “normal” one I dont think. On 8/7 I had unprotected intercourse. 3 weeks later I took a blood test and it came out negative. Would that possibly be a to early negative test?

If I take a blood test 25 days after unprotected intercourse would these results be accurate?
