I had sex on the 14th of September we were careful he didn't ejaculate in me I then had sex again on the 24th of September he ejaculated in me then and he did it again a couple days after that. They gave me a EDD of June 12,2013 I searched the web and they said I conceived on the 19th of September but I didn't I would have been a 3 weeks or a month in the beginning of October but I was admitted into the hospital October 15,2012 and the doctor told me I was at least two weeks pregnant. Could my due dare be wrong?

Conception dates are estimates, and pregnancy can happen without ejactulation, there are plenty of sperm in early fluids.

Dates of conception, can only be estimated give or take one to two weeks, so there is no way to be sure.

Oh OK just wondering because on the 14th of September we used a condom in fact we used 3 that night so no mishaps could happen but on the 24th-29th we were careless is it possible I got pregnant on the 24th of September?

You did not use "3" at the same time, that is the best way to cause a mishap, that is not how they are made to be used.

Condoms have a 3 to 18 percent failure rate, if you used more than one at a time, it will actually increase the falure rates.

But yes either date is possible, why the worry ?

I thought so but I talked to my doctor and he told me I could have conceived the 24th of September by my cycle being irregular my cycle length is 34 days he said they just based it off my first day of my last cycle
