Is it possible to start having nausea if you’re pregnant this early?

I’m currently cd 18 or 19 out of a 26 day cycle I ovulate early because of my short cycles and and I ovulated I believe on cd 11, would it be possible to experience slight nausea this early on? A few days ago I was cramping as if it could be implantation i understand that may definitely not be why I was cramping but if it was how soon after could someone be nauseous?
