Ovulation after Miscarriage 🥚🤰🏽

How soon after a miscarriage can you ovulate? I’m asking because I had a miscarriage 7/11 and it shows on an opk that I ovulated at the peak day yesterday. I didn’t think it could happen so soon after a MC. I’ve had heavy bleeding on and off since the MC. Still waiting to hear back from my OB if there is any hcg left in my system since I still have some clots and tissue discharge.

Help! Because if this is so my hubby and I had sex Monday which would have been pre ovulation... or a low day not peak.
