Ay common yan sa third trimester, lalo na around your weeks! A few of us mums experienced the same thing, it's usually just fluid retention and the extra weight, pero importante pa rin i-check with your OB to rule out anything else like preeclampsia, especially if sobrang puffiness or may high blood pressure. Isa sa mga kaibigan ko, hinawakan lang niya ang feet frequently at nag-elevate, pero talaga, better safe than sorry with pregnancy swelling kaya best to report it sa doctor mo sa next checkup.
