Ay mama, ang sakit ng tyan during pregnancy talaga ang hirap, lalo na first trimester pa lang. Since your doctor prescribed those for you, trust your doctor's judgment, they know your specific situation best and wouldn't give something na harmful sa baby ninyo. A few of us mums have taken heartburn meds during pregnancy din, but really, kung may concerns kayo about side effects or if the pain doesn't improve in a few days, follow up with your OB right away para ma-reassure kayo. Get some rest soon, and eat smaller meals muna to help your tummy settle. Sending you healing vibes!
