I'm 16 and theres this guy i've been seeing off and on now for about a year and well he kept trying to get me to have sex with him I kept tellin him no i'm too young and all this other stuff but he kept pressuring me and on march 16th I gave into the pressure and had sex with him. We used a condom but see it busted I dont know if it was like after he had taking "it" out or while "it" was still in me. Well on march 27th I started bleeding like it was my period but it only lasted about a day. I'm on a low dose birth control for medical reasons but sometimes I forget to take it but either way it causes me to have shorter periods but its usually lasts at least 2 days. I'm not having any symptoms like i'm pregnant but like it just seems like my stomach is getting bigger but i've heard that me stressing about it can cause some symptoms and cause me to miss a period is this true? I'm confused and I need help. And before anyone says this I know me having sex at 16 when I know i'm not ready and well giving into pressure was stupid. But please someone help me out!
