Baby will only suck on my finger…help!

Sha

3 week old will not take the 4 different brands of pacifier I have tried so far, she is only soothed by sucking on my finger! I don’t want to keep buying different pacifiers. Anyone go through this and successful with a pacifier? If so what brand?!

Edit: I know a lot of people are saying maybe she just doesn’t want one. But when she’s cranky she wants to suck naturally and the only thing that soothes her is my finger
