I got my period yesterday, and it's been very different this time around. I've always had inconsistent, so that's not unusual to me. Anyways, this one has been much heavier than usual. I've been bleeding thru a regular sized tampon every two hours. I've been having huge clots, they're not as bad today as they were yesterday. And today it hurts to put a tampon in. It's to the point where I stopped using tampons. Which I normally use, and have been only using pads today.... What could be causing this? Should I find a gyno to go to?
