I can understand how confusing it must be to be 15 and thinking you may be pregnant but here is a tip, why dont you try NOT having sex until you can understand FULLY the consequeces? I was 17 and I got pregnant, now I have a baby. I didnt even finish school and it was the biggest mistake I ever made. I love my daughter and she is the only thing that makes anything worth while but if I had a choice, I would definately wait until I had the patience and after I got at least SOME of my immaturity out of my system. My mom had me at an early age and she was hardly ever around for me. I love my mother but she was very selfish, she would leave me with 16 year old boys so she could go party and get drunk. I vowed that I would never be like that. And I lost my virginity when I was barely 16. My self esteem was very low, and I felt like my whole life was just crumbling. I was very fortunate that I didnt get pregnant then. If I were you, I would quit having unprotected sex, at least. If you ask the guy to wear a condom and he says no, he isnt worth it anyway. You are so much better than that, and I dont even know you. Just consider it or you'll be 15 with a baby and probably not man around (not saying your boyfriend will leave you, but most guys do - at least at that age) and it will be so hard. Think long-term.
Sincerly
