Is having rashes normal in pregnancy? Currently 30weeks and 1 day pregnant. First time experience..

Yes, i’m having rashes too since 2nd tri. I’m currently 31weeks. I was advised to see a derma by my gynae to get medications. I’ve tried aloe vera gel, Suubalm etc and it’s not working :( I was told by my doc it’s not PUPPP cos I don’t have rashes on my tummy.
