Period help

So I have recently turned 15 and I've been having my period for 2-ish years. However, my mom passed and I have nobody to talk to about well any period things. I have googled many things but I mean no girls answered it. So, I just hope some of you lovely ladies can comment. Why do my cramps keep getting worse and worse with every period? Like they weren't bad but recently I can't even more and lay crying and medicine won't work. Also, what if my discharge is a weird color? Its happened to be green a few times when I was sick. Is that okay?
