Period isn't normal

This period is really bad, I'm on really heavy and it's clotting and really painful. My lady bits are actually hurting. :( I tried having a bath thinking it will help belly stop hurting but it's worse. When I feel my belly on the left side I can feel a bump. It's really hard, it could be internal organs but getting scared. Feel really depressed at moment. Really want a baby but it's never happening. I'm 22 and fertile but been trying for a year, doing my heading now
