Because the 2 weeks before you ovulated/2 weeks after your last period are counted in how long you are pregnant. Pregnancy/gestational ages are counted from your last period, not when your baby was concieved.

When they go by the date of your last period, that is 2 weeks before conception. So the pregnancy actually starts 2 weeks before you conceive. When they say you are 9 weeks pregnant, that means 9 weeks from the first day of your last period, so you would have conceived 2 weeks later. If you really think too hard about the dates, it just confuses you. The due date is just an estimate any way.

You are 9 weeks pregnant. With pregnancy, they count from the first day of your last period so you are actually pregnant two weeks before you conceive making the baby two weeks less than what you are, so the baby is 7 weeks old if you are 9 weeks pregnant.

They date a pregnancy by the first day of your last period. But you really didn't ovulate till 2 weeks after that. So say that your last period was on the first of the month...you didn't ovulate till teh 14th of the month (this is when you got pregnant) but they cound the 2 weeks as if you got pregnant on the first. So being 7 weeks,,,you conceived 5 weeks previous.

the pregnancy calendar starts at the date of your last period. You don't conceive for approximately 2 weeks. So the first 2 weeks of pregnancy there is no embryo. according to doctors you are 9 weeks. according to actually having a living being inside of you you are 7 weeks. hope I made sense.

you are 9 weeks pregnant dating from the first day of your last period, this is how it is counted and its 40 weeks from the first day of your last period, the fetus is only 7 weeks old though because for 2 weeks or so you hadn't conceived.
The doctor's will class you as 9 weeks so that's what you count it by.
Hope this helps.
Good Luck and congratulations

your baby's gestational age is 9 weeks. docs start counting the day afetr your first period because they dont know when you could have conceived, this s gestetional age. but usually woman conceive about 2 weeks after the first day of their lmp. and thats why you have that 2 week difference. i am almost 36 weeks gestational but in reality i my baby has been in my tummy for 34 weeks because conception was on the 20th of april exactly 2 weeks after my lmp. i hope this helps

You're nine weeks as far as everything medical is concerned, all books and counters and stuff. Doctors like to complicate things, so they don't actually count it from when the sperm meets the egg.
