Ovulation after having a baby?

4 weeks ago I had a stillbirth at 27 weeks. My husband and I want to try again in the future for another baby but I figured it would be a while before I started ovulating again and having regular cycles. I ended up getting my period a week ago and now I’m cramping like I typically would when I ovulate and my discharge is like it typically was when I ovulated in the past. Is it possible to ovulate this soon?? Or does it typically take longer? This was my first pregnancy so I’m not sure what’s normal and what’s not
