Hello,
You seem to be having Pruritic urticarial papules and plaques of
pregnancy(PUPP). ). It is characterized by small red bumps and
hives, and when severe, the bumps form large patches. This rash usually develops on the abdomen, and spreads to the thighs, buttocks, breasts and arms. Slight itching from PUPPP may cause mild discomfort. However, PUPPP does disappear after delivery.
