Aw mama, you're definitely not alone, a few of us had rashes din sa late pregnancy, it's so common kaya don't worry! It's usually from the heat, sweating, or sometimes the skin stretching, pero since you're at 35 weeks na, best to mention it to your OB just to be sure kung anong type ng rash it is at if may treatment sila mareccommend. In the meantime, try keeping the area dry and cool, wear loose cotton clothes, at avoid scratching kung kaya mo (I know, easier said than done!). Let us know what your doc says, maraming kami dito na ready to share kung ano ang natulong sa amin!
