Test Not Picking Up Ovulation

Nikki • Mother of two angels & 1 rainbow baby, Lillian.

I'm on day 17 of my cycle. Breastfed our baby for a year so didn't have a period during that time. This is first cycle after that. I've had a blinking smiley face for several days now, but no peak day detected.

My question: Is it possible for tests to miss your ovulation day? ...or maybe I'm just not ovulating or it will be super late this month?
