Rashes around belly button

I had rashes and pimples from face to neck to chest to belly and back for my 1st pregnancy, complexion was terrible. I don't remember what I did but maybe you can try aloe vera gel or Topicreme. It'll be gone after the pregnancy. To compare with my other 2 pregnancies without the rash/allergies, my 1st born inherited the allergies till now she is 9yo (getting mild over the years). So I'm not sure does this pass on to baby. I'll only know after 4th one out cause I'm having rash here and there now.
