[heyy144]

k i got an ultrasound i am 13 weeks and 5 days pregnant today. i don't remember my last period . and im not sure if that ultrasound is 100% accurate. i wanna know if its possible that i conceived july 21 ? or did i conceive before july 21. because i am confused when i put the conception date july 21 on pregnancy calculators it always tells me that im 12 weeks is it possible that i conceived before july 21 in order for me to be exactly 13 weeks and 4days.

Guys, that was October 2010 lol, so at the time she would've been close to 13 weeks.

I concieved like September 4th or 8th and I am 28w2days.  If you are 13 weeks you did not conceive in July.

If u are 13 wks there is no way u conceived in July. I conceived in July. And I'm 36 +3.

i just think that my ultrasound my be a little wrong ireally dont remember my last period .

I am 13 weeks 3 days, and I know my exact conception date. I got a positive ovulation test on July 17th, which means I conceived on July 18th. On average, one ovulates about 24 hrs after a positive teat, and the egg only lives for 12-24 hrs from all that I have read. So you probably conceived on July 17th, the day before me. My last period was July 3rd.

the only thing that I can tell you is that if your ultrasound is correct on your gestation then your conception date is 7-15-2010
