TTC and confused

Hey all...I just need some guidance. We have been TTC for almost two years now. Here recently, I basically have given up and tried focusing on other things. Well, here recently, my breasts have become so tender that I can’t touch them and I am EXHAUSTED all. The. Time. I keep attempting to take cheap tests from amazon to get some answers, but they are all negative. I haven’t had AF since my last day on April 2nd. Now, I am 27 and was on birth control from 2009 until end of 2016. I guess I’m just not sure what to do. Has anyone had this happen? What steps did you take waiting for AF? Any advice would be spectacular.
