Do you still ovulate if you don't have AF's? I'm trying to work out my cycle but don't have AF's (last one was October 2003). I want to try for a baby girl and have read on here that you have to BD before ovulation. I have also found that different books/websites are contradictory, some say that you should BD before ovulation, some say on the day. I've purchased some OPKs that have the two blue lines on, when the first line is stronger that the second it means what?? This is the right time to try for a girl OR this is the time that you are likely to be ovulating and likely to get a boy. Have DS 1 already and have no idea whether he was conceived on O day or not. (was told that I probably couldn't conceive)! Hope someone can help.
