Honestly, mamsh, I'd check with your OB first before using Vaporub, kahit common ito sa atin, mas safe na tanungin lang siya kung okay lang for pregnancy, lalo na kaya you're in your second trimester pa. A few of us moms swear by steam inhalation or pregnancy-safe alternatives pag may cough, pero better safe than sorry talaga. As for gender, usually makikita na ninyo around 20-22 weeks sa ultrasound kung clear ang position ng baby, so you're right on time, excited ka na ba?
