There's no way to tell for sure. But doctors count the date of your last menstrual to determine how many weeks you are. Count two weeks past your last menstrual period and that would be around the date of conception which is when you were ovulating.
Technically if you're 34 weeks along, your baby is really only 32 weeks old since conception took place two weeks after your period.

They date your pregnancy from the first day of your last period, figuring the conception date was 2 weeks after that. For examply my due date is March 29th, My last period began on June 23rd, and my conception date was around July 4th. The conception date is not necessarily the date the sex occured, since sperm can live for upto 5 days, and the egg can be fertilized for 24 hours after ovulation.

if you get a due date from ultrasound, that is more accurate than LMP... go back 38 wks from the due date, and that is the approximate date of ovulation. insemination likely occurred sometime the week prior to ovulation, thru the day of. sperm can live up to a week, max. 5 days fairly easily.
