Uy, mama, I know how uncomfortable yan, pero dahil may pain sa left side at vaginal soreness pa, kailangan mo talaga magpakonsulta sa OB mo agad or mag-ER na lang para ma-check properly, ha? Hindi kami dapat mag-diagnose dito kasi may maraming possible causes, at you're 31 weeks na, mas better safe than sorry. Acid reflux in pregnancy ay common talaga, a few of us moms dealt with it, pero ang combination ng symptoms mo kailangan ng professional check-up para sure ka. Yakap muna, and please go see your doctor, wag mag-atubili!
