Is my period ok or is it just plain wacko!?

Nancy
So I started my period in 5th grade. I remember going to the bathroom during class and it wasn't like I thought it'd be. No crying , no crying in pain, and no cramps. Looked like I would of cut myself shaving and just let it be. , so I had emergency panty liners just in case ( smallest thing ever) but did the job til I got home. I told my mom about it and she shipped me to the store. We both got boxes of pads (she's one of those women who are scared of tampons and forced me to used pads til I was 17) ... Anyway it didn't last long 2 days with very little to no bleeding. Thought okay I'm just starting out it'd be different next time (my mom having planed when next time would be) I was ready for it this time. But it never came for 2 months after that day it was filled blown looked like somebody would of killed me.... Well here we are a whole 8 years later... Same thing still going on I will have little bleeding to no bleeding for two r three days , 6 to 9 months with nothing and then bam for two weeks to two and half weeks of heavy bleeding non-stop... Has always been like this is there something wrong with me!? 
Edit--- my last period hasn't been for three months and still nothing.
