Throwing up in the morning?!

I'm only on Cycle Day 11. We've been BD since my period ended 10/20. I know it's probably way too soon for morning sickness but I've thrown up once this morning & felt better after. Not sure if it will happen again or not, just wanted to know if this has happened to anyone & it actually be morning sickness.
