If you have never had intercourse and your period is late what would cause this?
when i was a teenager this happened to me a lot. Turns out I have endometriosis. But the dr said many things can cause it. Weight(too heavy or too thin) stress, many diff things. I would def call ur dr and ask what he/she thinks. Just to be safe depending on how late it is. SInce pregnancy is out, you don't want to ignore this.
