Im 19 years old and i started my period early. I have stumic pain, back pain, i throw up on the first day. I told my ex boyfriend and he thinks i could be pragnant. He was getting mad cause we both have a baby and he dosen't want another I don't know whats going on with me. Im really scared. I hope i dont have this pain when school starts I hope im not pragnant. Cause me and my ex are both senior in high school and we dont want another one yet. I just want to know what the pain is. Please i hope im not pragnant cause my family and my ex will get mad at me :'(
