Formula recommendations ?!

My baby is almost 3 weeks old. She has a super sensitive stomach. I breastfeed pretty much half the time and the other half is formula. We have tried similac pro total comfort and she seemed like she was spitting up a lot so she switched to enfamil gentlease . Seemed like it was better at first but it’s been like 6 days on it and last night she screamed for hours with lots of gas and will only stop when she finally poops which is once a day or once every day and a half. She spits up a looot and we can hear her stomach making noises and farting a lot. Idk what we should try now I hate to have to keep switching her. I hear some good things about enfamil enspire but idk how that is for stomach problems like this.
