Hi po, naiintindihan ko talaga ang worry mo kasi four years pa lang with thyroid and then pregnant ulit, sobrang stressful yan mentally at physically. Una po, the good news is thyroid condition ay hindi contagious sa kids, pero kailangan mo talaga ng close monitoring with your OB at endocrinologist together kasi pregnancy and thyroid ay kailangan mag-coordinate ng medications and dose adjustments para safe for you and baby. A few of my mum friends with thyroid managed pregnancies successfully but needed regular check-ups, kaya please don't skip appointments at be honest with your doctors about your hospitalization history last year, dapat alam nila ang full picture para ma-assess nila kung kayang-kaya ng katawan mo. Breathe po, marami nang successful pregnancies with thyroid, pero ito talaga ay case-by-case, kaya ang best move is to consult your doctors asap para ma-ease ang mind mo at ma-plan properly ang pregnancy.
