soooo...

so I had protected sex two weeks ago but the condom broke. I'm on birth control and I know that fails sometimes Expectaly if you don't get the kind your body needs. I've been gaining weight, puking almost everyday for the past week, my boobs are really sore and I've been having more discharge than usual. I'm going to go to the clinic today and get a pregnancy test. I'm worried and I kinda wanna be pregnant but then again I don't. any advice? could I actually be pregnant?
