The system to calculate a womans due date in the United States can be a little confusing. They will take the date of your last menstrual period and count forward 40 weeks to arrive at your due date. However, you are not truly pregnant for the first two weeks (and only 38 of the 40). This is why an ultrasound would show a 5 week old baby when your last period was 7 weeks ago. You will need to account time for when ovulation actually happened after your last period, time for the egg to be fertilized by the sperm, time for the fertilized egg to travel to the uterus and implant (this alone can take up to 6 days or more), and then, only after implantation does your body produce the hormone hCG and mean you are "really" pregnant. All of that can take up to two weeks.

If you were pregnant the developing embryo would be about the size of the head of a pin. The embryo is not the first sign of pregnancy found on ultrasound; the yolk sac shows up long before the embryo is visible. The yolk sac can't be seen uon ultrasound until at least four weeks after the last period.

Can you take an at home pregnancy test while having your period?

Yes, but if your menstrual blood comes in contact with the test strip it will not give you accurate results. If you have your period, you might not be pregnant. You should wait fourteen days after intercourse to take a home pregnancy test and get accurate results.

Why would you have an HCG level of 27814 and know you are 9 weeks' pregnant but your ultrasound only shows the fetus is at 6 weeks' gestation?

6 Weeks Gestation actually counts from fertilization. However many weeks pregnant you are is actually counted from the first day of your last period. So, when you are 20 weeks pregnant you are actually only 18 weeks gestation. You may of had your days wrong and you really is 6 weeks or they may be measuring your baby head incorrectly


How long does it take to get a positive test if you are pregnant?

You should take a test now if you are almost 2 months late. A pregnancy test usually shows positive if you are pregnant right after your period is missed.
