So I’m 17 years old and me and my boyfriend have been sexually active. This app says that my period was supposedly start on the 7 of this month. But it says that I am late on my period. We have one more week left of this month and I haven’t gotten my period. What should I do? I need some advice or someone to talk to. I can’t really talk to my family about it or my mom because I am not close to them.
