hey guys, this is my first time using OPK’s ( i think that’s what these are called) and the first day i tested ( tuesday which according to my trackers wasn’t considered a fertile day ) and it was a high negative bout 54%, then wednesday ( which was considered a fertile day due to tracker) was a high negative 39%, thursday 49%, and today 46% . i’m supposed to be ovulating on the 25-26th according to my trackers , is it normal for the numbers to fluctuate like this before i ovulate?
