Has anyone been through this... Every month I do OPK and u an yet to get a positive other than once... Which was the first month I was off the pill! I'm finding CM hard to read as I don't have a lot ever. According to BBT I ince ovulated on day 19 and then last month day 15... Is that normal? Meant to ovulate tomorrow but still getting negative OPK. Feeling so dispondant.
