Ay oo, ang swelling na yan super common sa third trimester kaya don't worry! A few of us moms swear by elevating our feet whenever possible, drinking lots of water (counterintuitive pero talagang tumutulong), and avoiding salty foods, one of my mum friends said na pag nag-reduce siya ng asin, napabuti agad ang puffiness niya. Pero since you're already at 28 weeks and concerned, best to mention it sa OB mo next visit para sure lang na walang other complications okay? Rest assured, maraming moms ang nakadikit dito and okay lang lahat after delivery!
