Af is a day early ttc #1

Sadly af came a day early than my glow expected date . So sad 😞 but I was wondering does that mean I ovulated a day early ? My clear blue opk gave me a peak on March 19, and af was suppose to start April 3rd according to glow .but I just got it today April 2.

Also In February we had bd on the day I got a peak but still didn’t get pregnant 😕 It’s just sucks. Ttc #1 in my early 30s 😞
