Confused about ovulation/period after chemical pregnancy

Bri

I had a positive OPK on December 8th so 10 days ago. I’ve been testing on and off. But I’m so confused as to when my period is supposed to come since I had a chemical? Does anyone know or have experience with this? I’m so confused with my body and I’ve always been spot on just “feeling” when I’m ovulating or getting my period.

I had a chemical pregnancy on Black Friday (November 25)
