Similac 360 total care

Moms! I need some feedback - switched my daughter from Similac sensitive pro to Similac 360 total care due to formula shortage and discontinuation. Initially everything was fine but now there is more spit up after each feed and poop at intervals of 3/5 days. The poop is liquid when it finally does come out.

I feel the delayed bowel movements are causing fullness in her stomach, resulting in spit up right after feedings. We burp and feed upright and don’t lay her down right away. Anyone facing the same issue?

Anyone have any suggestions on a good formula like this which just results in more frequent bowel movements and less spit up. It appears the spit up could actually be GERD but don’t know for sure.
