Getting worried!

My period is significantly late, by some months. I have taken 3 tests in the past month and they all came up negative? 
I do not have health insurance (I know shame shame) but I was told to go get a blood test done. 
I'm nervous, worried (I literally just quit smoking, and drank my ass of a few weeks ago) but I'm also getting my hopes up and getting excited before I even know anything! We want a child soooo bad, I know I shouldn't get my hopes up invade it really is negative and my body is just going crazy. 
I guess I just needed to get all this off my chest, we have been TTC for almost 2 years, and I want it pretty freaking bad, he wants it even more!!! 
Ahhhhhh i need to get my shit together! Thanks for reading my rant!
