Vomiting after trying formula?

Allie

I have been exclusively breastfeeding my daughter who is 11 days old. There has been many complications and I've decided to switch to formula only. I gave her one bottle of formula and she was completely fine and then the second bottle she vomited up, not spit up, like a lot of vomit. Is this normal? Just from switching to formula? I know it's a lot harsher on babies tummies.
