Ay, mama, I understand your worry kasi it's a big concern talaga. Pero ang good news, maraming moms with thyroid issues na nag-deliver ng healthy babies, ang key lang ay ma-monitor properly ng doctor mo throughout, kaya if hindi pa, please get checked ASAP para ma-regulate ang levels mo at ma-ensure baby's development ay on track. One of my friends had thyroid during pregnancy and her OB-GYN adjusted her meds regularly, kaya lahat went well naman. Laban lang, and keep communicating with your doctor about any concerns mo!
