Weird tight pressure feeling??

So I am 37 weeks and 2 days. All night I woke up every two hours very uncomfortable. I think I have pupps (see Dr on thursday) so I wake up itching but once I was awake I noticed how bad my back and hips were hurting. Nothing helped other than waiting for it to pass. Now today baby has been active and I've been feeling this weird uncomfortable almost painful feeling down low. It almost feels like a period cramp but not really... I'd have to describe it more like when your cervix is bumped but it's a consistent pain that comes and goes and varies in intensity.. I've been trying to figure out if it's my baby moving or if I'm having a contraction now as well. I feel my baby move and it almost feels like he's stretching but everywhere my belly gets more hard on the top center but not as much on the sides? I'm a ftm and was not dilated and baby hadn't dropped as of last week. Could this be a sign of him dropping?? Has anyone else experienced this?
