Hay, normal yan sa marami sa amin during pregnancy, lalo na third trimester kasi ang immune system natin ay nag-aadapt pa! One of my mum friends said she had non-stop sipon from week 28 onwards, tapos nawala agad after delivery, pero honestly, mas safe to check with your OB just to make sure it's not something na kailangan i-manage differently while pregnant, especially since you're coughing na rin. They can recommend pregnancy-safe remedies kung kailangan mo talaga ng something to help you sleep better, kasi ang tulog talaga importante sa third trimester!
