No period & BFN's daily 6 weeks after MC - annoyed and defeated

Diana
To the point where I dont know what my symptoms are anymore, why Im cramping, why my cm is watery, nothing at all makes sense in this limbo. It could all be pregnancy symptoms or pms!!! 
I had an ultrasound and passed everything, my period shouldnt be so long!!
We have litterally bdded all month!!! But sure enough! Bfn's only! 
I give up... All your god!
