I feel like I'm going crazy!

I feel like I want to cry and scream all at the same time. I'm nauseous all day long, my headaches increase usually at night to where I can't sleep. I'm bloated to the point that I get full really fast. Between the back aches, leg aches and abdominal pain I threw up last night so hard I bruised the back of my throat and looks like I almost popped a vessel. I've taken who knows how many test. Ones say no and ones with very very faint lines. Just this morning I took 3 accu clear tests and a clear blue digital. The accu clear all have faint + but the digital says not pregnant.
