Mama, if ang sakit mo ay matinding or may bleeding, please go to your OB or hospital agad, hindi dapat i-ignore yan in the first trimester. For mild tummy discomfort, the safest thing is to check with your doctor first before trying anything, kasi sensitive ang first trimester at kailangan sure na safe. Rest, light meals, at staying hydrated usually help, pero talaga, best to confirm with your OB what's causing it so you know what's okay to do. Wishing you feel better soon!
