Labor and delivery worthy?

So for the last 3 days I’ve been battling with the nausea and upset stomach as well as this just uncomfortable crampy feeling and these stingy pains that start in my back and wrap the front of my abdomen and sometimes down to my vagina. I started timing it last night and it was close but not 5-1-1 close so I just fell asleep due to exhaustion. I woke up feeling the same but it subsided a bit. I am now once again experiencing the same pain and I feel extremely bloated and tight. I don’t Necessarily get that tight contracting pain every time just an overall tightness and bloated ness. I just had a softer bowel movement and I have been sucking down water like crazy! So I know I’m not dehydrated. I am about to take a warm bath and start timing these pains I am experiencing again after. Is this contractions that I may be experiencing? If so is it worth going back to L&D? I was there almost 2 weeks ago for discomfort and I was having mild contractions but no dilation. I am 36+2 weeks today.
