Am I pregnant?

Hello everyone, 
For the past week and a half I have brig having a lot of bloating and a heavy sensation on my stomach alone with some disgusting watery mouth what makes me feel that I'm going to puke. Now my breast is very tender and it hurts soooo bad! 
My friend made me take a drunk pregnancy test very late at night, which came out with a very faithed negative. 
When I told her, she made it sound like it could be a bad test or it was because I was drunk lol or also too early to tell. 
I should included that I have a 8 yrs old buy and when I was 3 months pregnant of him all the home pregnancy test would come out negative. 
What do guys think?
