I'm due on March 12th so I'm not freaking out. I'm not throwing up just nausea all the time. I'm considering taking a test saturday if i don't have it yet. He did finish in me. twice. :(. I'm not sad about it, but I just turned 21!
The part that's a little strange is the nausea...are you legit dry heaving and throwing up? Or just feel sick? Did he finish inside you? Your symptoms don't sound like pregnancy, if you were pregnant you would be like 10 days pregnant which in "most" cases is way to early to have symptoms. For sure if you don't get your period by march 19, I'd take a pregnancy test, and use protection next time !! :)
