First of all, you said you have no been using condoms. I am 18 and just got diagnosed with hpv. Before it is too late, please, please, listen to me. You need to use condoms, no matter what. If your partner says he doesnt like them, or you dont like them, you need to use one. Because there is no sex worth getting an std and having it for the rest of your life. Being pregnant is the least of your worries, I highly doubt you are. I think you are just worrying yourself. I did this plenty of times when I was 15, you worry yourself so much that you convince yourself your stomach hurts and you stop eating so you lose energy. Just go get tested, and please use condoms. You do not want to get an std!
