Period helpppp

Okay ladies so, I've had a period for ten years now. I'm 20 years old, and I've always had a long and heavy period. Between 6 and 8 days long.

This last period only lasted 4 days. The second day I actually bled like a period. But only for a day and a half. I am NOT on any medications or on birth control. My fiancé and I are not smart in the sense we use the old "pull-out" method.

Shortly before my period I had thrown up once after eating a few different items.

But I thought nothing of it cause I figured it wasn't sitting right with my stomach because I ate so late at night.

AND what also scares me is, during my period my fiancé and I do not use any method of protection, not even the "pull-out" method if y'all can understand what I'm getting at.

This happened twice.

I need advice!!!
