Aw, kababata mo pa lang at ang heartburn na agad! Nakakaubos talaga, lalo na pag may sumusuka pa, a few of us mums went through the same sa third trimester kaya alam ko kung gaano kakasakit. Pero since umuubo na siya at parang lumalalaki, I'd really suggest checking with your OB soon because sometimes the vomiting can be a bit concerning, especially kung it's affecting kung kumakain ka ng maayos. Hindi ka mag-aalala sa prenatal vitamins mo, pero your doctor might want to recommend something safe para sa acid mo or check if may iba pang nangyayari, walang masama sa pag-consult, makakatulong lang yan para matulog ka ng maayos ulit! In the meantime, try eating smaller meals more frequently, and avoid spicy or oily stuff (yan ang nagsasalita ng experience hehe). You're almost there na, mama!
