Vomiting ALL day.. Could I be pregnant?

Hi everyone I had a little bit to drink about 6 beers on Saturday night the next day I woke up and had the spins and what I thought was a huge hangover which didn't really make sense considering I didn't drink much and I never vomit the next day. Sunday morning I had diarrhea and I vomited about five times I also had chills. My last period was about 2 weeks ago.. Could I be pregnant?
