Don't know if it is normal

I'm am 34 weeks pregnant with my fourth child. This pregnancy has been a lot different than others. For the past two days I have been miserable I have been having painful cramping. I've had it before and brought it up to my doctor and they didn't seem to concerned. I'm to the point that it hurts so bad I can't get comfortable to sleep. 
I honestly never had this my other pregnancies. I feel dumb asking peoples opinions because this is my fourth pregnancy. This is new to me though. He has been have been active. I have no spotting or bleeding. I do feel like he is moving inside my vagina which is also different. It's like he is scratching me when he moves.
