Hi Dana,
The rash could be anything from *****ly heat to an allergic reaction. Just try putting something like calomine lotion on it, or if it really bugs you go to the chemist and ask what they can recommend.

My first pregnancy my skin chemistry changed so much that when I sweated, it burned my skin like acid and I ended up with big welts of blisters everywhere my clothing rubbed my skin. The only thing I could do to be able to sleep was apply cortisone cream - nbt really recommended, but I was desperate.

Good luck, and remember that it's only for another few months!
