Aw, yan talaga ang struggle ng third trimester! Kami sa mum group namin, dami nagsabi na nangyari din sa kanila around this time kasi lumalaki na yung baby at nag-shift ang weight distribution, super uncomfortable talaga. Try mo yung pelvic support belt (marami sa pharmacy), at make sure ka naman mag-rest ng maayos, avoid prolonged standing, at practice gentle stretching na safe for pregnancy. But honestly, mommy, better check with your OB about this para sure na okay lang and hindi something that needs attention, especially since you're na close na sa due date, better be safe!
