So I had this dry spell where I wasn't wet at all for like 3 months. Now all of a sudden I'm wet again like I used to. And there's of white creamy discharge. Dx
My period is due soon ,I've never had unprotected sex. So wtffff is happening >< it became a little yellow, but doesn't smell bad.
Sorry the tmi
