Pregnancy Week 1: Menstruation

Pregnancy is calculated from the first day of your last period and not from conception.  As a result, during week one of your pregnancy you are not actually pregnant. You count day one of pregnancy from the first day of your period.pregnancy week one

So, what’s going on in your body during that first week?

On average, a menstrual cycle is around 28 days, with 21 to 35 days being the normal range. The first week of pregnancy (assuming you become pregnant in any given cycle) is mostly menstruation a.k.a your period. Hormone levels are at a low and are telling the body it is not pregnant, so it is shedding the uterine lining and preparing for a new cycle.

What should you be doing during the first week of pregnancy?

Now is the time to begin acting pregnant. How do you act pregnant, you ask? We don’t mean in the stereotypical vision of eating ice cream with pickles, but to begin taking prenatal vitamin vitamins and cease any drug and alcohol use. The condition of your body affects your new baby even before he/she baby has been conceived. Make sure your dad-to-be is also being health conscious at this point. The health of his sperm will also affect your baby.

You may also consider basal body temping as you are officially trying to conceive. Basal body temping can help you determine when you ovulate in a given cycle and increase your chances of becoming pregnant. Keep in mind that only about 25 percent of all couples make a baby in that first month of trying–it may take awhile.
