Yes because the first two weeks your not considered pregnant.... For example if your ultrasound measures the sac at 5 weeks you actually are 7 weeks if you count the 2 weeks it take to conceive and implant.

Doctors add two weeks onto your pregnancy because it is quite difficult to determine a woman's exact time of conception. So they start your first day of pregnancy from your last period, even though you aren't actually pregnant yet. It makes it easier and more simplified for determining how far along you are in your pregnancy which will help determine the due date. For most women, they ovulate 14 days after their period. Ovulation is the perfect time for conception. It is not until two weeks after you have conceived that your hcg levels (pregnancy hormone) will be high enough to give you an accurate positive result through testing. So by the time you can determine your pregnancy, you are generally four weeks pregnant.

I think because it takes that long for the sperm cell to actually divide into the egg, after it sits for several days?

Why do you add 2 weeks for gestation?

Its not like they just add 2 weeks, they measure from your last period and its 40 weeks from that. Most women have a 28 day (4 week) cycle and since you usually ovulate around the middle of your cycle and that's usually about the time you conceive, its like the basically add 2 weeks from when you probably conceived. So for purposes of counting, its sort of like your 2 weeeks pregnant when you conceive. seems crazy but that's how they do it.
