Odd Discharge

Hey guys. It's been kinda weird. For my fertile window, I've been having this sweet smelling, milky white discharge and I'm so confused. I've definitely had discharge of this color and texture but right now it smells so sweet and its flooding my underwear! I thought I was on my period! And, ok I'll be honest, I taste my discharge to see what it's like down there. Usually it's a bit sour and tasteless, but now it's like absolutely nothing! Like slimy water almost. Has anyone else had this kind of discharge? It's so weird, I have no idea what's happening. Please help.
