Belly rash ??

Montana • baby Mavy

I was putting lotion on and I realized I have some sort of rash going on all over my stomach??

Does anyone know what it could be from or how to get it to go away?/: my ob can’t get me in until my scheduled appointment on the 10th so SOS lol

It’s really itchy and quite red, sorry for the low quality pics, I couldn’t get a good picture to show all the bumps and redness
