Uy mama, heartburn at breathing difficulties sa pregnancy ay common talaga, pero kung feeling mo talaga na mahirap huminga o sobrang init ng dibdib, please go see your OB or go to the ER, better safe than sorry lalo na nandyan na ang baby mo! A few of us moms experienced similar pag umabot na sa third trimester, yung baby ay lumalaki na kasi at nag-press sa organs mo, kaya ang acid reflux at heaviness sa chest, pero importante talaga na i-check ng doctor para sure na okay ka at baby. Once cleared ka, may tips ang doc para ma-manage, like eating smaller meals or sleeping elevated. Wishing you well, mama!
