OPINIONS!!! Please?!

Ok.. So AF was due 4/27, took a test that morning with FMU and it was negative! I shook it off and said maybe we didn't succeed this month and went along with my day! Well it is now day 35 and I have had absolutely no sign that AF is coming! I have had a constant medium/heavy CM.. I feel like I'm peeing on myself all day everyday (sorry TMI).. I don't know if this might be a sign or not?! I have had a strange taste in my mouth for a few days now, I'm exhausted but push through, I am also emotional.. Crying from a song on the radio, a movie, or even DWTS dances!! I'm not usually a crier! I don't want to get my hopes up and make my body think that I am pregnant when I'm not! This month I haven't really tracked because we have had a lot going on with my mom's cancer and her being in and out of the hospital! I want this so bad but I don't wanna work myself up! What should I do?!
