6 days of high on OPK and no peak!😳

I've been testing with Clearblue ovulation kit and I'm on my 6 day of getting high (flashing smiley face) and no peak. I got pregnant  twice (and mc twice) with these tests and always got a high on my 3 o 4 day after flashing smiley. Am I not ovulating? 🙁 just got off the pill, I was on it for 3 months! Please help!
