Pregnant or not? Please help!

Has anyone just really felt like you were pregnant had symptoms such as
-temp between 98.4-99.6 for the past few weeks
-white discharge then light brown
-constant bloating
-sore breast
-bleeding gums
-horrible back ache
-dr. told me I was constipated
-hot flashes
About a week before my period I spotting brown and watery red for a few days , period was due the 8th, nothing. started spotting again the 16th. It stopped yesterday. Now just light brown discharge. Has anyone had something like this before? Were you pregnant or not? I just have this gut feeling that I am, but I've been getting negative tests. And if I'm not then why I'm i having all this?
