Pregnant?

E • Baby #2 coming May 2016 IT'S A BOY!! 😄
I was hoping someone could relate to my symptoms before I decide to go into the doctors looking like an idiot. I've tried taking a pregnancy test but it came out negative but I've never had these symptoms before so I can't tell what this could be menstrual cycle or possibly pregnant?...My symptoms are nausea, mild cramps, severely sore breasts, I'll get cold then hot and I'm extremely tired.
