So, came off my period about 6 days ago. I am also on birth control(trinessa). My boyfriend and I had sex twice within the past 5 or 6 days. I woke up in the middle of the night last night around 3:30am and threw up a little. I have been feeling pukey until about a half hour ago.(about 10am). now its mostly gone. I never have ever gotten sick to the point where I throw up and then feel better withing even a day. I am a paranoid person to being with, is it possible I am pregnant?
