Okay guys so I recently started the pill (I'm on Tri-Sprintec) and I think I'm on my period? I usually have fairly heavy periods. The one I had when I started the pill was one of the WORST periods ever. This one doesn't seem existence. I get like a streak on a pad so it's not even heavy enough to use tampons....any advice or anything?
