Oo normal yan, sis! At 28 weeks, maraming changes ang nangyayari sa body mo kaya parang mas maraming discharge, a few of us pregnant friends namin noticed the same thing. The important thing is kung wala siyang strong odor, hindi siya itchy, at clear or white lang, you're good; pero if it's yellowish, greenish, or may weird smell, definitely mention it sa OB mo next visit or call na agad kasi baka may infection.
