Im deathly afraid and have skipped school for the past two days because im scared. ): please help me! I have been freaking out for the past 2 days, i even left school today because i was guna throw up becuase im scared shes pregnant, me and her where just messing around, i was masturbating her and then we wanted to know what if felt like, so i took my penis out and put it on her vagina, i did not put it in, not at all. just touched it. I may have had pre *** on my penis but not positive, we are both virgins, never had sex before nor have i ever put it in her. Shes on birth control for acne which im unsure if it prevents pregnancy, im pretty sure its the same stuff. Im only 16 and i cant handle a child in my life, nor can she. I think im just scaring my self and worrying about nothing but please tell me if im okay and that shes not pregnant, is she pregnant or not?! im really scared and have been feeling sick for the past few days. please help me ): Please tell me if i should worry or not I have been worried sick for the past 2 days and need some help, i need positive answers ): She had craving for toast yesterday, and was a little sick the other day, then again this happened 2 days ago and dont think its related. should i be worried or should i just carry on with my life, i now plan on waiting to have sex until im older. please just help me out and tell me if she and i are okay. I have been throwing up scared. Im really worried and cant stop thinking about it, what should i do! ): im using this as a lesson and plan on never messing around again. just please help me out guys! Like i said, i never put it in her and i didnt ejaculate. Shes on birth control and she told me she takes it every day. should i be worried or just calm down? im really scared.
