Ay oo, normal lang yan sa pregnancy! 23 weeks ka pa lang pero ang dami na ng blood flow sa pelvic area kaya parang swollen pakiramdam mo, lalo na towards the end of the day or pagod ka na. A few of us mommies namin noticed din yan, especially pag mainit o standing long hours. Usually nag-improve ang feeling with rest, loose underwear, at pag-elevate ng legs. But since worried ka, better check with your OB just to be sure, baka ma-recommend lang niya ng pelvic support or cooling pads, pero it's good to mention it sa next visit para peace of mind mo!
