What it is
It usually goes away by itself within 12 weeks, though skin colour changes can last longer.
Moisturisers, steroid creams and antihistamines can ease itching. It is worth getting checked in pregnancy.
Common signs
- One larger pink or dark patch first (herald patch)
- Many smaller oval patches after days or weeks
- Itching
- Feeling tired, a headache or a mild fever beforehand
How it is usually diagnosed
- Looking at the rash
- Sometimes a blood test to rule out other causes
Records worth keeping
Keeping these together makes each appointment easier, especially when you see a new doctor:
- GP or dermatology notes
- Photos of the rash over time
Questions to ask your doctor
- Could this be anything else?
- What can help with the itching?
- Do I need to do anything in pregnancy?
When to get help right away
Call 112 or go to the nearest emergency department if you have:
- A rash in pregnancy, or a rash with a high fever and feeling very unwell: see a doctor the same day
