Quoting The Inconspicuous Raccoon:" I've been getting them bad! SO and I had sex last night around 3:30 AM and I was contracting until almost ... [snip!] ... though Went to the doctor today & I'm not dilated at all. As far as easing them, I don't know. I just try to sleep."
Ouch that sucks, I had a lot of false contractions with both of my previous pregnancies, they never got very painful though. Went overdue both times
Good luck OP, maybe just avoid sex or orgasm if you can't find a way to deal with them. If they don't go away though, and get closer together you're probably in labor.
