1 month pp and might be pregnant!!

I am horrified that i might be pregnant again! My newborn just turned a month!! Me and my fiance waited exactly a month to have sex and he came inside of me.. He sucks at pulling out. The thing that scares me the most is that I had a c section and I know you are supposed to wait 6 months to have another baby.. What harm can it due to my body. It's only been a week since i had unprotected sex and i was losing so much weight and now im gaining it.. And I still eat the same.. And im so bloated now.. I wasn't before and my appetite has increased!

Has anyone has c sections back to back? Im so scared.
