Oo normal yan sa pregnancy, lalo na pag tumatagal, a few of us din dito sa mommy group namin experienced the same thing around that stage, kaya don't worry! The increased discharge is just your body's way ng preparing, pero since may slight odor siya and it's cloudy, better mention it sa OB mo next check-up para ma-rule out any infection like yeast o bacterial, kasi sometimes those things can happen during pregnancy at nakakainsan lang ng peace of mind na i-confirm na lahat okay.
