Worried ? Clear discharge

I'm having LARGE amounts of clear discharge , that actually drips sometimes when taking my panties off... it doesn't really have an Oder , more of a natural smell , I'm really tired , getting a little Sick on my stomach at times , I have had protected sex since last AF. Boyfriend didn't actually cum, and used a condom.  My clit area itches at times .. I'm not sure if it's my cycle changing maybe. Or what .. but I never have this much discharge. Kinda scary to me.  AF was due Friday the 31st of this month.  Still waiting.
