Aw, mahirap talaga ang sipon habang buntis! Honestly, the safest approach is paracetamol lang para sa headache (check with your OB on the dosage para sa pregnancy), and I swear by saline nasal drops or spray para sa congestion, a few of us preggy moms use that para safe, walang worries. For the body aches at general discomfort, proper rest, lots of fluids, at warm soup talaga ang best bet, pero pag persistent pa rin or lumalala, better check with your doctor agad para sure na okay lang everything. Get well soon, mama!
