Hi mama, congrats on your pregnancy! Honestly, baking soda can be okay for general cleaning (like sa bathtub para sa itchiness), pero since 5 months ka na, better to check with your OB muna kung specific ba ang reason mo, like if it's for yeast infection or skin concerns, may safer options na specifically safe for pregnancy. A few of my mum friends had skin issues during pregnancy din and their doctors recommended gentler alternatives, so mas peace of mind lang talaga if you get personalized advice from your doctor. How are you feeling otherwise?
