I cheated on atkins and I feel like crap :/ ?

I'm on day 10 of induction and I was at a wedding yesturday and I tried just to eat the meat and I gave in and had a thin slice of strawberry cheesecake and a tiny bit of mashed potato and a bit of stuffing, I felt so bad that I went to the toilets about an hour later and made myself throw up a little, I never make myself throw up and never will again I just felt so bad, have I gained any weight? Or will I be okay if I start induction fresh tomorrow?
