It's Normal to get acne in pregnancy dear, I too used to get. My skin is oily n prone to breakouts so I get pimples often too. Just take care of the face well, have a dedicated CTM routine, use good cleanser for the face daily, gel moussant variants are good. I use Bioderma sebium gel moussant... Doesn't give me pimples. Then tone with rose water n apply a moisturiser. Eat less oily n spicy food, it will help with pimples too
