I am 16 years old, about 2 weeks ago i'm not sure if it was rape but it was forced sex with one of my so called friends, it was unproteced an he pulled out a cummed about 2 seconds after he pulled out. I am on birth control but the past few days I havnt been feeling well an been getting light headed and I missed my period, i'm to scared to tell my mom what happend she doesn't even know i'm having sex yet, I really want to tell her but i don't know how to
I am sorry to hear what happened to you. If you told him that you did not want sex with him and he still did it, it is rape.
As long as you have been taking your pills as you should, the chance is extremely small that you will be pregnant. It may be worth your while to get tested for an STD. If he did this to you, he probably engaged in unsafe sex with other girls.
My suggestion is that you do tell your mom. You need some support from an adult that cares for you.
