Uy, nakaka-iba talaga mag-sipon during pregnancy, kaya get well soon! Ako personally, nag-rely lang ako sa fluids, pineapple juice, warm water with honey, at tulog, para hindi maging dahilan pa ang gamot, pero honestly best talaga magcheck sa OB mo para sure na safe ang ibibigay niya, especially for the headache & congestion kasi iba ang rules when preggy. A few of us mums tried steam inhalation din (hot water sa maliliit na tasa, cover mo with towel) at it helped with the nasal stuff without meds. Take care ha, and don't push yourself, rest is really your best friend ngayon!
