Ay, that sounds stressful, mama! But good call mo na nag-follow up with Internal Medicine, seryoso talaga ang thyroid levels especially during pregnancy at labor, kaya okay lang na may second opinion ka na from another lab. A few of my mum friends din nag-worry about their thyroid results, at honestly ang dami nang options ngayon para ma-manage ito safely, so trust your doctors na. Keep those follow-ups and updates with both your OB at Internal Medicine, they'll figure out the best plan para sa iyo at sa baby. Kaya mo yan, mama!
