THE EFF WAS THAT?!

So I had stomach cramping and aching so bad, I woke up out of my sleep (AT 6 IN THE MORNING!!!) !!! I laid there for a couple of minutes trying to ignore it. Nausea sparked so bad I had to make myself throw up on an empty stomach. Is this morning sickness? Could I be pregnant? I had unprotected sex on my most fertile day and the day after, and a few days after that. If you're wondering If I was having any symptoms, the underpart of my breat hurt, and my cm has increased in quantity slightly.
