Sayang, uterine fibroids during twin pregnancy memang boleh jadi tricky, especially when they're positioned lower, best thing is to have a proper chat with your ob-gyn, they can monitor things closely since twins already need extra attention anyway. From what I hear from mum friends, most fibroids don't cause big issues during pregnancy, but yours kena monitor regularly je to make sure they don't interfere with the babies' growth or labour later on.
