Emotional before BFP?

So AF isn’t due until the 23rd/24th (I’m approx. 8/9 dpo and had a little blood when checking CP at 5/6dpo) and I’ve been a mess the last couple of days! Yesterday I woke up literally crying. Wet pillow and all. From a silly dream. Then this morning my fiancé wanted to eat chips and I said “don’t make a mess on the couch”.... to which he replied “this is MY couch and I’ll do what I want.” He laughed and I know he was joking SO... tell me why I cried. Instantly.

I’m normally not this emotional. Ever. I hate that pre AF signs and symptoms can mimic bfp signs and symptoms! Ugh! Anyone else get super emotional over silly stuff and wind up getting a bfp?
