Calia - you don't have to answer if it's too personal, but is there a diagnosis on why it's taking you guys so long? I remember some of your story, but not all. Â Simistar - I just started using the CBFM last month too, but it was only as successful for me as OPK's (ovulation predictor kits) were. I did them side by side, so I could compare and my OPK's always gave an almost + the day before my definite + and then an almost the day after and those were the days the FM told me too. So I'm really glad I didn't pay for it, it was a gift from my husbands cousin who bought it but got pregnant before she could use it. However, I know that other people get a bigger window from using it, or the OPK's don't register a positive for them ever, so I think it is a good tool, it just doesn't offer me anything more then a regular old internet cheapie OPK does. Â Oh and don't feel bad about late ovulation, the earliest I have ever O'd was CD17, but I average CD20 with CD24 being my latest. And my LP ranges from 9-14 days long which is abnormal. And my cycles range from 25-36 days long. They are all wacked out after my ectopic pregnancy and loss of my left fallopian tube last June.
