Formula reaction? Tmi poop

My daughter just started having these poops. This is not her normal. She is one month old. Just changed to formula almost 2 weeks ago. She will have a poop like this, I'll change her. Hear her tummy gurgle and then she blows out. She is pooping at every feed but not just once. THREE-FOUR TIMES every feed. Within minutes of each other. (I can't wait to change her to be sure she is done, she poops SO much it's a blowout almost everytime. This much or more and very watery. Sometimes more than others. No fever. She is on Similac Pro total comfort. Could she just be reacting to the formula? I know they say 7-10 days and we are just a few days past it now. Help please! I'm changing her instantly and slathering her in butt cream and her bottom Is still so raw. 😭 she gets really fussy right before each one.
