Baby belly problems?

Ella

My baby is 7 weeks old and suffers from gassiness and constipation more recently. I give her Gerber soothe drops with probiotics thats good for her digestive health but it's only been like 5 days since I started. Her belly be super full and she struggles to fart and her farts smell awful. She poops usually once a day. She's formula fed and I had read somewhere it was normal for her to poop 1-2 times a day but now I don't know. Any tips to help her at least poop better? I've tried everything for gas. I've even tried belly massages, leg bicycles, tummy time. Helps a little but not enough
