QuestionHI, AT THE TIME I AM VERY CONFUSED AND MY DOCTORS ANSWER HAVENT REALLY HELP ME OUT MUCH.
MY LAST PERIOD STARTED NOVEMBER 2ND, 2009. TODAY FEBRUARY 9TH, 2010 I AM 13 WEEKS AND 1 DAY FOLLOWING MY LAST ULTRASOUND. N HERE IS WHERE I GET CONFUSED...
EARLY ON MY PREGNANCY I HAD SOME COMPLICATIONS AROUND CHRISTMAS WEEK AND BECAUSE OF THAT I GOT SEVERAL ULTRASOUNDS, THE DOCTORS WERE CONCERN BECAUSE FOLLOWING MY LMP AT THE TIME I WAS SUPPOSE TO B 8 WEEKS PREGNANT AND THEY WERE ONLY SEING A SACK. ON DECEMBER 30TH I WENT BACK FOR AN ULTRASOUND AND THEY GOT TO SEE A 6 WEEK BABY W A HEALTHY HEART BEAT. AND THAT DOESNT MATCH AT ALL MY LMP. 3 WEEKS LATER I WENT BACK FOR ANOTHER ULTRASOUND THINKING THAT I WAS 9 WEEKS BUT NO MY HEALTHY BABY MEASURED 11 WEEKS AND THEY CHANGED MY DUE DATE TO AUGUST 15, 2010. ON NOVEMBER I HAD INTERCOURSE 3 TIMES, NOVEMBER 10TH, WHICH IS THE ONE THAT WOULD GO WITH MY OVULATION DAYS, NOVEMBER 22ND, AND NOVEMBER 27TH.
MY QUESTION IS WHY DID THE GESTATIONAL AGE OF MY BABY CHANGED FROM ONE ULTRASOUND TO THE OTHER ONE? AND WHEN WAS MY CONCEPTION DATE?? BECAUSE IF WE FOLLOW MY BABYS GESTATIONAL AGE DOESNT MATCH W MY LMP... N SHOULD I TRUST MY ULTRASOUND AND THE DUE DATE THAT THEY GIVING ME??
THANK U!!!

AnswerHi Sandra,
Generally I would say go with the ultrasound because early ultrasounds are very accurate when done before 12 weeks, however since they keep changing the gestational age on you, maybe it would be more helpful to just use your LMP of Nov. 2nd for calculations. Using that information, I get the following:
First Day of Last Menstrual Period: November 2, 2009
Probable Date of Ovulation: November 16, 2009
Possible Dates of Conception: November 12 to November 20, 2009
Due Date: August 9, 2010 (40 weeks)
As to why the ultrasounds are not matching up, all I can say is that scans are not a perfect science, nor are the technicians who do them. It's possible that one of them was done by something with not much experience in reading them, and their measurements were off.
