Hi everyone, I have been off the pill now since Jan 07 and my cycles are really long. About 6-7 weeks and I never know if I have O'd or not. Last cycle I tried OPK for about 2 weeks when I thought I should O but they all came back negative and my cycle was 7 weeks long that time. So haven't bothed this time as I didn't have a clue when it would be. After reading on this site and other places about the signs of O I noticed on Sunday, Monday, Tuesday that my CM had changed and last night I did a OPK and it came back +. So last night I made sure we BD, unfortunately we never BD on Monday night but did on Sunday. If the OPK was + yesterday then when would have been the best time to BD? I hope I didn't miss out on the Monday!!!! Also is there anyone else who has long cycles or did have and tried something that made them shorter?
