Please read 32 weeks crampy

Li
So I am basically 32 weeks (31w5d) & for the past two, going on three, days I have been crampy. Crampy as in period cramps and center/upper back pain on both sides that I can only describe as cramps. I am a FTM so I don't really know if the way I am feeling is normal or not. I am going to the docs on Monday but I am wondering if you ladies suggest I go in early. My period cramps are slightly consistent, maybe every 40 mins and last for about a minute. My back cramps however, are very consistent and have been basically all day with the exception of a few hours cramp free. My stomach tightens with some of the period cramps, and sometimes (most of the time) it's just cramps. Advice? My baby has been moving, I have been staying hydrated in case it's from dehydration but they are still occurring...
