Cycle change / ovulation post baby

Layne

Did anyone else’s ovulation day change after having a baby? I used to get my period 14 days after my positive OPK day. I’ve only had one period since having my baby 15 months ago. I’m waiting for the second one. I had a positive OPK 16 days ago and no period. I took a pregnancy test but it was negative. Maybe I’m ovulating earlier in my cycle? Or the OPK was wrong (it was digital).
