Formula issues

My daughter is two months old now.

We’ve been supplementing since she was about two weeks old with the regular Enfamil liquid formula, but about a week or two ago she started refusing it (along with her Gripe water) acting like it suddenly tasted disgusting. We had some samples from similac so we started giving her the Pro sensitive since she’s had a bit of trouble with gas (We used to give her gas drops, but recently she gets violently upset if we give it to her more than once a day, like it’s hurting her). Ever since we started giving that to her she’s been severely bloated and fussy. I’m not sure what other formula to try, we also have some of the Similac pro advance but I’m almost afraid to give that to her in case it might do the same thing.

Any suggestions on what kind of formula we should try giving her? Her gas isn’t terrible anymore (without that formula) so I’m not super concerned about that right now.
