I also got quite painful BH with my third. I thought I was going into labour every second night with contractions 5 mins apart but then after a few hours they would start to slow down. The only way I can describe the difference is that in real labour they are more intense and seem to keep getting harder to stand through even if they dont get closer together. Sorry not much help here.

I hope something happens for you tonight. You could try a bit of nipple stimulation or sex when you start getting regular contractions again. They both can help things along.

Good luck!
