Can't believe I'm back trying for number 3! Can't even remember what to do! I fell more or less both times with my first and second baby, and this is our second month of trying. I think I was little out with my dates last month, so I've been using cheap and digi OPK's this month. I'm currently CD20. I got a positive cheapy and digi (smiley face) on CD 18 (Valentine's Day!!!) and have BD'd on CD15, CD16, CD17, CD18 and CD19. Haven't had a positive OPK since the 18th and my digi OPK's say best chance of conceiving is if I DTD on the day of the positive test and the day after. Wondering if I should get another one in for good luck tonight? Though we're both knackered and all out of romance hahaha...! Any advice?
