From bf to formula

Hi fellow mommas. I’ve been breastfeeding/pumping for the baby since she was born (3months). I stopped pumping a week ago as it was only leading to constant engorgement and discomfort due to me not being able to commit to it (I go back and forth to my in laws house a lot, they live four hours away). I decided to only have baby at breasts instead of bottle but have been doubting that maybe my baby hasn’t been getting enough milk because with this growth spurt she’s been really fussy, has intervals where she refuses the boob and wants bottle (I give her bottle with milk collected from Hakka pump but it’s not a lot). I pumped today to give her a bottle but there was hardly any milk coming out. Seriously thinking about formula at this point. Are any of you mommas going between breast milk and formula at the same time? I’m thinking of doing breast milk all day with one bottle of formula a day? Kindly share personal experience if relatable or any advice. Also if you’re a mom who is doing formula and breast milk plz do share suggestions on what brand of formula to use (most similar to breast milk). Thanks in advance 💖
