Extreme nausea and vomiting?

I’ll be 10 weeks tomorrow, up until tonight I haven’t thrown up at all. I noticed this past week I’ve been extremely nauseous, much worse than all the previous weeks. It makes eating extremely difficult and I thought I felt worse just from eating less. Is it normal to start throwing up around 10 weeks? I googled it and it said to talk to the doctor if you start vomiting at or after 10 weeks which makes me think somethings wrong. Has anyone else had this happen? This is the first time I finally feel some relief from this awful nausea.
