Wa'alaikumassalam sis! Thyroid during pregnancy memang kena monitor closely sebab boleh affect baby's development, tapi the good news is dengan proper medication and regular check-ups, most mums deliver healthy babies je. Kawan saya ada hypothyroidism, dia kena adjust dosage during pregnancy and deliver perfectly fine, the key adalah consistent dengan doctor's appointment dan blood tests. I'd suggest kat your gynae or endocrinologist confirm your medication is pregnancy-safe and they monitor your TSH levels regularly, because treatment yang proper really makes a difference for baby's brain development. Have you started seeing a specialist or did your OB mention anything specific about your condition?
