Normal lang yan, sis, white discharge during pregnancy ay super common, lalo na kapag may movement ng baby! A few of us mums noticed the same thing, especially around mid-pregnancy like you at 22 weeks, kaya don't worry. The important thing is kung walang bad smell, walang itching, at walang pain, then you're usually good, but since you want to be sure, it's always best to mention it sa OB mo sa next check-up just to be safe, okay? Kung suddenly may weird odor or color changes, that's when you message your doctor na agad-agad lang.
