We tried to conceive for months.. Twice a day during ovulation windows, every other day for entire rest of cycle except AF.. Finally gave up after 6 or 7 months, used condoms for a few months because I wanted to be able to drink without worrying.. Then one month we decided not to use condoms but because we were kinda fighting a bit we only DTD like 3 random times all month... And boom, preggos. And I think the bd that did it was standing up in the shower and washing myself afterward lol go figure... I now am a firm believer in not stressing it and leung Nature decide, because despite the stats, it only takes one time.
