Rough morning

A :)
A little long. I was woken up about 3am with severe back pain from neck to bum. After trying everything to sleep I succumbed and sat in the living room to watch tv. Now the past few days I've been having some cramping and pretty emotional. I've been chalking it up to AF coming soon (11/15 expected). I spent Thursday night watching my favorite show and cried the whole time. Well this morning I was watching an animal vet show and started crying when a rabbit was brought into the office. I've never been this emotional in the time before AF. Of course every month I swear it's my month and I will get a bfp. Am I just having an extra crazy cycle or could this actually really be?
Also how do you stop yourself from inexplicably crying at the drop of a dime??
