please help asap

I am currently 29 weeks pregnant. My LMP was 7/5/12, and I had sex on 7/3/12 & 8/4/12. I am almost positive that I got pregnant on 8/4/12 because, as I said, I had my period a month before & it was very heavy, which is normal for me. My concern is that maybe I'm wrong.. but if I got pregnant the month before I'd be further along, right? I'm thinking either I'm irregular or my egg lasted longer than normal- which is possible cause everyone is different. I just want to reassure myself of the approximate date I conceived. Please help!

Thanks for the help. But, based on the prior info, which sounds more likely? I'm just a little nervous about it.

The Drs put you two weeks further along than you actually are. Say if you are 4 weeks along they will put you at 6 weeks along. I guess that's because not all women ovulate at the same time and they go by when your last period started. Your first ultrasound should have said exactly how far along you were when you had it done. There's a calculator here somewhere on MH. I'll try to find it for you.
