Help.? any advice.

Alright, sooo, my nipples have been like really, really sensitive, I feel like they might be a little swollen and I have been feeling like really weird in my stomach, like it feels like I have that hungry feeling, but I'm not hungry, I am like always tired, I have been super emotional and I've been nauseous on and off. My husband thinks I could be pregnant, I don't want to think I am and not be, and I have had a couple of dreams about me taking a test and it coming out positive. I have taken a test about two weeks ago (keep in mind I got it from the dollar store) and it was negative. I just need any suggestions or advice.
