possible morning sickness? pls help.

Sable • Hi.. Uh.
I had unprotected sex around 6-8 hours after ovulation, and definitely he "finished" if you will, inside me. And it's about a week after that and I've never been so ill in my life? Like I had to run out of a store just to prevent vomiting. And it's happened every night since. And mild cramping. Is it even normal to feel anything this early?
