Vomiting on Birth Control?

So I recently stopped my birth control (because covid19 I was also social distancing from my bf and not sexually active/didnt wanna waste my pills). I had been off of it for almost two months and restarted it 5 days ago. The nausea hit me on day 3 which I was used to because when I first started birth control a year ago I had bad nausea then as well. The only thing is, back then I only vomited like once per day. This time I vomited 3 times tonight alone. Is that normal?
