A cup of martini

Okay so yesterday we went to a restaurant and they were giving out free martinis so I got one, I didn't drink it fast; I drank it at a normal speed. Then we got in the car and I immediately felt nauseous. My mouth started watering and I ran into his grandmas house and threw up in the bathroom. It wasn't just a throw up of the martini it was of all the food I had had that day. It was just gross and sorry for the tmi but could that be a sign of pregnacy? My boobs have been aching crazy lately! And my vagina is swollen. Any suggestions?
