Ovulation after early MC?

Hi, I miscarried last month, first pregnancy ever. I bled for about 5 days and I would say I’m roughly on cycle day 11 now. I’m <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> again and tonight I took an OPK and it looks to be like I’m only like a day or two away from a blazing positive. Could it be picking up leftover hcg? I took another pregnancy test as well and no line at all was on it. Is it possible to ovulate again shortly after a miscarriage?
