Can you ovulate after first post partum period

My daughter just turned 1 year last week and I got my first post partum period Sunday. It was kind of light and it ended on Tuesday.

I’m still breastfeeding so I know the return of fertility can be slow, but I’m wondering if I will start ovulating again this month. I was irregular before pregnancy due to PCOS, but I’m hoping I’ll get lucky and my cycle will regulate itself soon. We’d like to start TTC baby #2 this summer. Just wondering if any of you ovulated and had regular cycles after your first post party’s period.
