I am 17 yrs old, and I think that I am pregnant but i'm not sure. Is there anyone out there who can help?? Well... Here is my story. Im on birth control but I never take them at the same time everyday, and i've also missed a few, well... Alot!! About 2 wks ago I had unprotected sex with my boyfriend the day after I got off of my period. I took my b/c earlier that morning but we had sex like 11 or 12 that night, I had no more b/c pills so I had to miss 2 until I got some more. Everyday since then i've been having lower back pain, abdomen pain, my sides hurt, my stomach constantly hurts all day long, headaches (basically all day), my breast are sore sometimes but not always, and they look as if their getting bigger. When I lay day my breat bone, or my chest hurts alot. One night I was drinking kool-aid, and I just had this feeling that I wanted to throw up, and I never have that feeling. It looked like I was spotting today the color was brownish, red and i've never had that. My period isnt do for about 2 or 3 weeks. So... Am I pregnant or am I just thinking that in my head. And should I stop my birth control or just keep taking them??
