Hoping this it!

Hi everyone!
​I am trying to conceive baby # 3 ( first two I didn't "try" to they both just happened but this one I am tracking ovulation and doing everything I need to on those days. 
​I have been having waves of nausea, extreme fatigue, sensitive smells, sore boobies, and my stomach is hard and bloated/ extended.
​I am due for my period April 26 ( in a few days) however  I have been taking home pregnancy tests and they have all been negative. Am I just testing too early and just reading too far into this???
