I need to ask a question about my dang chart. I have been using OPKS and there has been a line there but it has never turned positive. I just don't know if I think FF got my O date right, I'm not sure if I have even o'd at all yet cause my CM is picking up just now, and I have been checking that everyday. I have been having a normal cycle the last few months but I just don't know about this one so can I please have some input
