If my conception date is 4/17/06 why is the doctor telling me that I am 15weeks?

Answer 1

Your doctor goes by the date of your last menstrual period since conception dates are more of an estimate than an accurate and known fact. And so when your doctor says that you are 15 weeks, the first 2 weeks of those 15 is when you were probably getting to ovulate, so you weren't technically pregnant at those first 2 weeks. But like what I said, to make it easier for doctors they have to make a standard rule or guideline when it comes to counting your gestation period or weeks, and it's easier to go by the last menstrual period.

Answer 2

Your weeks of pregnancy are calculated by the date of your last menstrual period (LMP), not by the date of conception. This is a standard used by all practitioners because it is usually a far simpler matter to ask a woman when the first day of her last period was than to determine the exact date of conception. Not all women ovulate at the same point in their cycles. And too, conception is not a "visible" event like a period is, so there is less margin for error. So you basically wind up adding two weeks onto the conception date to get your weeks of pregnancy. The "standard" pregnancy lasts 40 weeks from the beginning of the LMP (or 38 weeks from conception, assuming a regular cycle and ovulation on day 14).

Answer 3

isn't that the most retarded thing in the world?? i asked the same thing myself the other day. I KNOW i was ovulating mid May so that makes me just 8 weeks this week. but the due date is calculated from the first day of your last period. why they add those extra weeks is beyond me. according to that math, that makes me 11 weeks. then you add on the 4.3 weeks that are actually in a month. With this thinking, i'm wondering if pregnancy is not the 40 weeks they say it is. since they insist on adding those 3 extra weeks. and technically in an odd way this makes some sense because on that calculation, it would explain why i am already feeling baby movement this freaking early!! look at it this way...according to the doctor's calculation, i will be delivering a whole 3 weeks earlier!!

Answer 4

The number of weeks into the pregnancy is calculated from the first day of the last period, not the date of conception.

Answer 5

theory dates are purely considered estimates for countless motives. first of all, even familiar cycle women people received't ovulate on Day 14 each month. it may decision extremely, everywhere from Day 12 to Day 16 for a familiar female on a 28-day cycle. different motives theory dates are in basic terms anticipated include: Sperm life should be as a lot as 3 to 5 days. rigidity or different life ameliorations can replace even familiar women people’s cycles for that month. Eggs take 12 to 24 hours to be shed, so the anticipated theory date ought to correctly be off by skill of in the destiny. recognizing at implantation should be mistaken for a very last neglected era, throwing off theory date by skill of as a lot as a month. once you've been conserving music of your basal body temperature, you need to recognize the dimensions of your luteal area--otherwise properly-called days previous ovulation. A mild upward thrust interior the body temperature shows that ovulation has got here about. the days between ovulation and the day beforehand your next era are considered the luteal area. inspite of if cycles are abnormal, DPO frequently continues to be an similar. therefore, you are able to count number lower back using your DPO to commence estimating theory date. the purely thoroughly precise way of understanding theory date is even as infertility remedies, which includes synthetic insemination or in vitro fertilization remedies were used. once you've had multiple companions interior both weeks surrounding your mid-cycle, you need to judge getting a paternity try.
