My boyfriend and I have been trying to conceive for this month... I have been taking my prenatals for a month now. I began using my Clearblue Digital advanced opks on sept. 1st (3 days after my period ended)... I got low fertility on the 1st, and high fertility 2nd-4th. On sept 4th, I tested in the evening and was given a PEAK result... I had to wait the 48 hours until I could test again... sept 6th exactly 48hrs after the peak I tested again and was shown low fertility, which I assumed I had ovulated during the weekend. I woke up and tested today (09/07) at 11:45am (Fmu) and received the high fertility result again... could there be a reason why I peaked on Friday but got high fertility again on Monday morning? Thanks in advance.
