Aww, normal yan sa pregnancy kaya don't worry too much! A few of us moms got rashes around this time din, it's usually just hormones and skin stretching, lalo na sa second pregnancy kasi mas mabilis ang pagbuo ng baby. Since hindi sya nakakagat at wala kang ibang symptoms, baka pregnancy rash lang talaga, pero mas safe na i-check mo pa rin with your OB just to be sure, lalo na since concerned ka sa baby, better safe than sorry, diba?
