Pregnancy way to soon post c-section

I just had my second baby 3 months ago! I’m EBF but got my period back already ugh 🤦‍♀️ I had a very traumatic birth with this baby boy. His cord prolapsed and we had an emergency c-section with tons of complications on my end. Thankfully, baby boy was great!

My incision site opened up a few hours after the operation, so my healing has been a little delayed and different compared to others.

I’m terrified of getting pregnant again! Im on birth control but that doesn’t calm my fears.

I’m so scared to even have sex because I keep hearing stories of failed birth control.

What would happen if I were to get pregnant again? Like within 6 months. Would my uterus burst open ?
