Is this normal? I normally get my +opk between cd 19 and cd 20 but im having a werid month. I have had very dark opks aince cd 13 and just when i think the next one has to be positive id get a light opk then very very dark again until yesterday when i got 3 positive looking tests in a row (over the course of the day) this is my first month tracking bbt and nothing looks like a pattern to me i did wake up and lay in bed awake with my mouth closed for a few mins this morning before realizing i was awake and needed to temp so todays could be slightly off but can anyone tell me is this normal for a bbt chart?
