Help!!!!!

38 weeks pregnant with my first I keep getting on and off tightness in my stomach some cramping but mostly back pain took a hot shower to see if that would help it relaxed me for a min now I’m starting to get that feeling again. Feels like I have to use restroom.

I live 35 min from hospital and don’t want to go until I know it’s the real deal could this possibly lead up to the real deal mind you I’ve been having on and off tightness for about 3-4 days now.. It has lasted much longer as of right now and I feel some what a shortness of breath let me tell you this was hard to write because of how uncomfortable I currently am..

What should I do?????!??? 😫 Anyone experience this before having their baby?
