7 weeks PP

Had c-section July 9th. Second kid. Stopped bleeding at 3 weeks PP. Hubby & I had sex probably 3-7 times between 3 to 7 weeks PP. Unprotected. He did pull out. (Yes, I know that doesn’t work.) Almost at the 6th week, I wiped and had light pink and some spotting for a day. Nothing else. On the 6th week, I had yellow discharge for 2 days. No odor, no itch, didn’t burn, but I am ready to get the DEPO. I can’t unless I start my period. I go see my PCP on Wednesday. I took 3 test, all negative. So maybe I’m in the clear and my body just needs time to get back to itself? I just know I really need a form of BC.

P.S. I know that you shouldn’t have sex before 6 weeks
