Ay, oo girl, swelling during pregnancy is super common, especially around weeks 18-20 onwards kaya walang kailangang mag-alarm! It's usually dahil sa hormonal changes at yung water retention na nangyayari sa katawan natin habang lumalaki ang baby. Pero since you're asking and it's bothering you, mas better check with your OB para sure lang, sometimes kailangan lang ng extra precautions like elevating your feet, drinking tons of water, at avoiding too much salt, pero iba-iba talaga per person. Ganyan pala ang pregnancy, lagi may mga surprise hihi!
