Hi, im 15 years old. I am not a virgin anymore. I lost it to my current boyfriend. About 3 weeks ago I was extremely stressed thinking that I was pregnant. I told my mom, I took a test. Thank God it came out negative. A week or two later I got my period, but it was a lot of bornw discharge. It has happened to me before but not as much only in the beginning. So in my period it was mostly brown, but when i went to wipe myself there was redish discharge [ sorry for that! ] So my mom is still asking me if there is a poissble pregnancy. I am not stressing or thinking about it much because I know I am not. But, what I also think might be that when I lost it for the first time to my boyfriend, I didn't bleed. Could that be why I had a lot more brownish discharge then red? Also, I've been getting headaches and sometimes vomiting. Could it be something else or is this a mischarage? Please someone help me. Your answers will be very much appreciated.

p.s. I am a waistress and the job there is a bit stressfull I have had shoulder pains and my co-worker said it was because of the job. Maybe could that be causing my headaches ?
