Hyperthyroidism ?!?

Bella
Any other mommas out there with hyperthyroidism?? I'm 12w 5d with twins and I was just diagnosed today with hyperthyroidism and they said I will need to take medication I don't go  in for a week to get the prescription. I'm worried for my babies. I wanna make sure that they're healthy and safe. Does anyone else have experience with this? Or any advice??
