Help is appreciated haha! :)

The other week it was "my time of month" and I started having intense pains, they gradually worsened over the minutes and lasted a good hour and a half, I then vomited a few times. The pain ended up dying off around half an hour later, after I had vomited though.

I am not on any birth control.

Does anyone know if there is a problem, may I be lacking something?
