My cycles have been 35-37 days long since coming off birth control in April. Today, I'm at CD 41.. I've gotten 2 negatives on FRER. One on Thursday and one this morning. I had a few days of bad cramping (especially in my back, but just on one side) and just knew AF was about to show, but that's been gone for about 3 days now. Anyone had a similar situation and ended up being pregnant after all?
