Colic or normal?

Am

FTM and LO is 2 weeks 3 days and is so fussy in the afternoons. How do I know if it’s colic or normal behavior? Nothing soothes her except breastfeeding and then she won’t stay asleep. We just gave her a pacifier today because we couldn’t calm her down, but it’s not something I want to continue because I worry about nipple confusion. Any suggestions?
