Help!

So when I lie in bed I have really bad back aches ( which has never done it before) and during the night I have to pee so bad it hurts my stomach even when I haven't drank anything, & I pee a ton & sometimes it's cloudy. I haven't had my period since May 21-25 & I took PT and the are all BFN's. I cramp in my lower tummy, it has been making loud gurgling sounds, & I have a lot of discharge. My breasts don't really hurt until you touch them a certain way & sometimes they tingle (but I barely feel it) I have frequent head aches.  What could be going on?
