Question

how many weeks are we technically pregnant from conception...i thought it was 38 weeks thats what i read..which is nine and a half months..but since the doctor adds 2 weeks from last menstrual period it is really 40 weeks right?

Answer 1

40. I am positive - five children and I know the hour and minute each were conceived, and delivered.

Answer 2

It is 38 weeks from conception. They generally assume your conception to have taken place 2 weeks after the start of your last period. (that's why they always ask you when your last period started). Therefore, the blood, tissue, etc in your uterus is already two weeks along by the time the actual fertalized egg is implanted. So that's why they say 40 weeks. Very few people know exactly when they conceived--well, maybe they do these days with all the ovulation kits and all, but basically doctors start with the first day of your last period and go from there. So your placenta is 40 weeks but the baby is 38.

Answer 3

You are correct. From conception to birth is generally, but not always 38 weeks. From menstruation to birth adds another two weeks. Doctors go by the extra two weeks because they are not certain of the actual date of conception. They choose an event that is hopefully well known by you as a reference point. There is the chance that you ovulated at some other time in your cycle. That would also throw the time off. It really isn't that important. Nature will usually take care of development and the time to be born. A week here or there won't matter.

Answer 4

From the date of conception it is 38 weeks. 40 weeks if you count from the LMP(last menstrual period). It is assumed that you conceived two weeks after the first day of your LMP, this also assumes that you have a normal 28 day cycle. Although you can get pregnant at anytime, even while menstruating, most women are most fertile and conceive two weeks after the LMP. The only way to tell for sure when you conceived (if you don't know when you conceived) is an ultrasound performed in the first trimester, if performed in the second trimester it is not as accurate because all babies grow at different rates and it's harder to give an accurate estimate.

Answer 5

It's kind of a trick question. Medically, pregnancy is considered to go from your last menstrual period until delivery. That's about 40 weeks - but coneption doesn't happen until about 2 weeks after the last period, so you're not actually pregnant for the first 2 weeks of the 40.

Answer 6

Your doctor counts 40 weeks, yes, but you don't know (usually) when you conceived. If you had a regular 28-day cycle, and you ovulate right smack in the middle, then, yes, 38 weeks from conception to due date. Or 40 weeks from LMP.

Answer 7

Yes it is 40 weeks. You would be starting your 10 month.

Answer 8

You are concieved first. As long as two weeks later your embryo is implanted into the uterus. From then on it takes 38 weeks to develope. So, therefore, it takes 38 weeks from implantation, but 40 weeks from conception.

Answer 9

40 weeks.

10 months.

Answer 10

if you go from your last menstral period than it would be 40weeks. counting the first two weeks of your cycle that you were actually NOT pregnant.
So when you deliver the baby the fetal age is actual on 38weeks. So yes, you are technically 40 weeks pregnant but the baby is only 38weeks old

Answer 11

it can be anywhere from 38 weeks to 40 weeks. after 40 weeks doctors usually want to induce labour because by that time baby's organs specially lungs are fully developed and ready to start breathing. so you can expect to go into labor any time after 37 weeks.
