It's practically impossible to diagnose a rash without seeing it, so I always tell pregnant women that they need to see their health care provider if they have a rash and don't know what it is. Your rash could be many things, from benign heat rash to an allergic rash to a rare type of rash that occurs only during pregnancy, but the very best thing for you to do is to see your health care provider quickly for a diagnosis. It's best not to use any over-the-counter ointments or other treatment for your rash until you see your provider. Some over-the-counter treatments are not to be used in pregnancy, and some can actually make some types of rashes worse.
