First ovulation after stillbirth?

First time using this type of OPK, it looks like I'm ovulating? I gave birth to our baby girl Rainier who was born sleeping on 10/6. She was 21 weeks 3 days old.

I havent really had a period though, just spotting last week. For other still born moms, did any of you ovulate without a period first? I would be so happy to know my body is coming back and we can start trying for another baby.
