Hi everyone. I'm new to The Bump. I got my BFP on Friday the 26th. It was a huge surprise and we're so thrilled! We were actually going to start TTC in Sept! My question is according to my calendar where I've been tracking AF since Feb '11, AF started July 29th and was over Aug 1st (strange period! usually they are 6 days long for me) I O'd on the 13th and my "most fertile times' were the 8th-13th. DH and I DTD on the 2nd, a whole 7 days before my fertile time and 12 days before O. We did not DTD the entire O week and then started DTD daily on the 17th. I can't get in to see my OB until Sept 19th. They will not see me any earlier because I am not high risk. So, I was wondering could I have O'd at a completely different time? Or could we have gotten pregnant in July instead of august? Or!! Can sperm really live for up to 2 weeks before fertilization and an egg for days after O? I am so confused as to when I got pregnant!
