Aiyoh sayang, congrats on the positive UPT! Tapi this is really something you need to discuss with your doctor ASAP, they'll want to know the exact timeline and can reassure you properly. A few of us pregnant mums took boosters at different stages, and our docs all said it's okay, but yours needs to review YOUR situation specifically. Jangan worry dulu, many women get boosters around early pregnancy and everything turned out fine, but please make that appointment soon so you can have peace of mind, okay? Take care!
