Am I??

I had my period a little over a week ago. In fact I started 2 or 3 days early. Now my boobs hurt so bad & feel super heavy. I'm also nauseous often and Wednesday I had acid reflux so bad I vomited. Is it normal (if I am, not sure if I am) for all of this if I am pregnant? Also, my wedding ring is cutting into my finger! And about how far along am I supposed to feel these symptoms. I took a test yesterday but it was negative, but it may still be too early. What do you guys think??
