Aih, I feel you! A few of my mum friends actually kena the same thing during pregnancy, hormones betul2 boleh trigger skin conditions macam psoriasis and dermatitis, it's so frustrating. Kesian la, masa dah pregnant heavy jugak nak worry pasal skin kan, tapi best is you see a dermatologist soonest sebab some treatments boleh affect baby, especially the strong steroid creams, they'll know which ones are safe for your trimester. Lepas tu, try to keep your skin cool and moisturised, avoid trigger foods or stress kalau boleh, and some of us find that natural moisturisers help when flare-ups happen. Do get it checked out ye, jangan self-medicate during pregnancy.
