Period After Pregnancy

When did you ladies get your first period after giving birth? I breastfed for 3 months and now am doing formula. My daughter is now 4 months old and I haven't had mine yet. I bled about 6 weeks after giving birth, but nothing since then. I did have a third degree episiotomy though when giving birth and it took me 8 weeks to heal from that. My husband and I want to TTC #2 but don't know if I'm fertile or not. I had PCOS and Endo before getting pregnant and didn't know if it would still affect me after birth or not. It took us 6 years to conceive our daughter. I just don't want to wait that long for #2.
