Needing answers!

I had my baby via csection a month ago. Last week me and my SO had sex and the condom broke! I'm so scared! I know you are supposed to wait. But everyone is different. So I just need opinions on how fertile are you three weeks after having a baby. I have not had my period since having the baby but can you still ovulate? Please no judgement on me not waiting my six weeks. I really just need some advice.
