BFN but symptoms?

Brittany
I've tested (only 10dpo) of course I got a BFN, I'm having weird watery Cm but it's cloudy. Like a LOT of it. Boobs are sore but not that bad, Af due the 20th. I've been REALLY depressed this past few days. Can't seem to stay happy. I want to cry constantly. Last time I got my BFP I was 2 days late without realizing it. I have no idea how I didn't calculate that. I lost my pregnancy (chemical) but my husband knew something was wrong because I was being a major B for a good week. Anyone else have similar symptoms before a BFP?
