Femara/ Ovulation

Hello! I just took Femara 2.5 mg on cycle day 3-7 for the first time. My doctor told me to BD starting cycle day 12, for 10 days, every other day. Ive been using ClearBlue Advance Digital ovulation tests since Saturday and for the past 4 days, they’ve all been HIGH. Saturday I had a low. Im starting to think it may not be accurate.

I’m wondering if any of y’all have had this happen to you? Or what cycle day did you get a PEAK?

I have PCOS and do not ovulate on my own.

Thank you!
