Rash on bump?

[PrincessJenga]

I'm 34 weeks pregnant and a rash has come up all over my bump. It's been coming on for the last few days but has been faint and kind of 'under the skin' until now. It's now bright red and really itchy.

Anyone had this? DP says I should try anti-histamines. Are they okay in pregnancy?

It's probably PUPP. Search on here or google for tips. Not dangerous at all for you or baby but a total PITA. Anti histamines may not help and most not recommended. I had a cream solution which I had to mix with menthol crystals, see your pharmacist. You have my sympathy!!
