Okay so I've been having my period for 10 years. My periods haven't been the most regular but typically last 4-5 days and come every 29 or 30. I've always had clots in my period but more recently I've noticed them more frequently and some have been bigger than normal. I get pretty bad cramps usually but they are manageable. I'm 20 and I'm home from school for Christmas break. I'm sexually active with my boyfriend but I am not pregnant. I'm not on birth control yet (working on it). But could the clots be something bad? Should I be worried or is it normal?
