Spit up

Jessica • Having my first baby due on June 18
My baby for the last 2 days has been spitting up after burping but prior to this really did it here and there. I was wondering if ok and maybe I'll get yelled out but I did try a baby teaspoon and not even of rice for 2 nights and I stopped it because of the spit up. Do u think it was to much to soon? 
I only tried the cereal just to satisfy her because she can eat
