My first child, i had all those symptoms, in 1995 of july he had got a high record of it being 104 degrees, in wisconsin. but the few days b4 that was in high 90's. My place did not have air conditioner. I went to hospital they sent me home, i get home and have all those pains, the HEAT was making me feel terrible and everytime i got to hospital and cooled off pain went away. I thought i was gona die in my small apartment so on the 13th i went to hospital and begged them to induce me lol. It was not fun having the heat play tricks with my body like that.
Well if those symptoms go away with rest, then its braxton hicks. Labor pains do not go away with rest, it progresses with rest and with activity
i had my daughter early as well. the dr. told me i wasnt ready but he checked again 30 min later i was dialated from 1 to 7. go w/ your instincts.
I have no idea but wanted to wish you good luck, and help bump up your post.
