Help formula advice

Destany

My formula fed baby cries all day. Nothing will soothe her she’s 6 weeks old I’ve changed her from Similac advanced (blue can) to Similac sensitive( orange can). I put gas drops (little remedies) in every bottle nothing helps she farts like a grown man and she keeps a tummy ache. She also always get the hiccups and spits up after almost every feeding. I’ve also tried gripe water(little remedies) she’s just so unsettled and cries for hours on end I need some advice should I change her formula if so advice on Similac soy or similac alimentum ? Or I’ll take recommendations on other brands of formula? Has anyone else been through this what has helped I’m at my wits end and will try anything to help my sweet girl😩😰
