Ladies I am currently on cd14 my BBT was 97.2. My question is my cycle is normally 30 to 32 days I started using OPK yesterday, both lines are there but they aren't positive yet. I was wondering around what cd day should I see my BBT dip and ovulation start to occur? And also the two apps I use say my fertile window is the 1- 7, to make sure we stand a chance we started BD every other day since cd 11
