okay so around the second week of july i had sex with an ultra thin condom. he said he checked it and it was fine but he was kinda dumb lmao. i'm suppose to get my period in 5 days and i'm seeing stretch marks and sometimes feeling cramping. can pms start this early ? and i'm having some discharge down there so i don't know if i should be scared or not. would you be able to know if the condom ripped?
