Gassy angry baby

So my baby is constipated and super super gassy. Only has 2 bowel movements on a good day and 0 on a bad day. Just added prune juice to her bottle yesterday hasn’t done anything yet. I swear it’s the neosure so I started doing sometimes neosure and sometimes just regular similac at first it started to work and she was having good poops…… now it’s constipation and crazy gas again. Anyone recommend the neurópro (purple in pic) or the gerber good start gentle? I got them as samples and I’m thinking maybe I should try a formula that is made for gassy fussy babies. She seems so uncomfortable! Any info or help is wanted! I did some tummy massage and lots of bicycle legs but haven’t tried any gas drops or anything like that yet.
