Is my baby sick?

So my daughter is teething so she has been fussy for a few weeks now. Today she may be a little more fussy. We gave a Normal bottle of formula about 2 hours ago and she has been doing nothing but spitting up. Yes, I burped her and she keeps spitting up like 6-7 times since her last bottle. She has been eating oatmeal cereal for about a week now, no issues. No other foods yet. I’m just worried she is sick since she is spitting up so much. She doesn’t feel warm but I haven’t taken her temperature.
