Confused and not FTM lol

I had my doct appt today and expressed my concerns about my excessive pains like major bad cramping, etc. He didnt want to check me, which I was fine with cause I know that can make it worse and do not want that. But he did say how hot its been I could be over doing things or be dehyrated. He told me if I keep feeling pains this bad to go to hospital and get checked out and if its during mid day to call and see if I can come in to be monitored.

But seriously since being in doctors office talking to him and being home for an hour, im still freaking cramping so bad off and on. Its awful.

Does anyone else experience this and when do I know to actually go in? Am I suppose to be hurting this bad? I dont want to go in just to be told im having Bh. Yes i have been drinking a ton of water because Its been so hot.

I only ever had contractions when I got induced with my dd and pitocin made them come on way fast so I dont feel like I really know.

Thanks to anyone who helps!
