I am 18 years old and my boyfriend and I want to have sex except that I want to have some type of protection and that's not condoms. My friend has it and it has worked perfectly for her. My question is, what happens after you get the implant? Does your period come right away? For how long? I have a lot of school events coming up mid-May and i wouldn't want to be on my period then also. That's why i want to know.
