Help...

I just had a baby 2 weeks ago.

An was told not to have sex until the bleeding stopped. My bleeding stopped about 6 days ago and decided to have sex with a condom today. Well the condom broke during sex and he came in me by accident. We had no clue it broke until after🤦🏻‍♀️ now where freaking out!!! I’m 17 we are not ready for another child just yet I’m curious I hear your were very fertile after birth. But I also took a ovulation test yesterday to also prepare for today and it was very negative, but I really hope I’m not still able to get pregnant...Oh and I am also breastfeeding. I get my iud tomorrow as well. Please just looking for help not judgement.
