Red bumps ( rash )

This isn’t pregnancy related but I’ve recently broke out in these red bumps on my body about two weeks ago! At first they weren’t itchy at all but now they are ! I have a 9 month old and a husband and they are fine ! So I know it’s not contagious. It seems to get worse when I’m hot . My husband thinks it’s a stress rash . I can’t get to my doctors until we go back home on Wednesday . Was hoping someone on here could help out! Please I’ve looked up everything and it does seem to be a stress rash but if anyone has ever had this happen I’d really appreciate the feedback. It’s starting to go down to my legs!
