Does my newborn have colic?

I have a 2-week old big guy (was 10lbs 5oz at birth)! I'm using formula because feeding didn't work out for us (he was never satisfied). We used Good Start in the hospital and it seemed to work well, but we changed to Parent's Choice Premium when we got home because it was on the cheaper side but just as good as Enfamil. We noticed a few days after using that he was a little gy (farting alot and fussy), so we tried Parent's Choice Sensitive...but within 6 hours he was screaming and crying after drinking 2oz, so after changing him, burping him, swaddling him, everything...we gave him 2oz more and he was quiet. We changed back to the Parent's Choice Premium because I didn't like how he was acting on the Sensitive. SOOOO...about a week later now, he's acting the same again. About 15min after a feeding, he's screaming bloody murder and we've tried EVERYTHING to soothe him...as soon as we put another bottle in his mouth, he's quiet. What's going on here?? We're using NUK bottles with airflow technology. He eats an average 23oz in 24 hours and sleeping about 11 hours in 24 hours. I've tried giving him gripe water, but it didn't work and he broke out a little on his face! I'm seeing his pediatrician tomorrow but wanted advice to hold me over until then! Thank you!!
