Hey mama! Ito talaga normal during pregnancy, ang hormones mo kasi go haywire and mas maraming discharge ang expected, especially as you progress sa pregnancy. A few of us mums went through the same thing and honestly, it was one of those things na walang warning sa mga prenatal classes hehe, pero it's totally fine as long as wala namang weird smell, color, o itching na parang hindi normal (like very yellow-green or may cottage cheese texture). Since it's your first time though, best to mention it sa OB mo just para ma-ease your mind and confirm na lahat good, hindi ka nag-aalala lang, alam mo na talaga lahat okay sa baby! Congrats sa pregnancy, mama!
