Hello, guys. I'm 17 and it turns out that my period is kind of late. It should have started 4 days ago and now I'm stressing out about it. I haven't done anything sexual in my life so this can't be the actual reason why it isn't "showing up". My period is ALWAYS on time, it even comes 2-3 days earlier. I don't know what is happening but I feel like vomiting and I'm so scared? :(
