Girls, hello, have you ever encountered such a problem?

Girls, hello, have you ever encountered such a problem? In general, I give formula after breastfeeding in 30-60ml amounts, it's the 14th of the month, and the pediatrician prescribed formula because the baby hasn't been eating enough. However, after we ate, she throws up in large quantities, sometimes even through her nose, have you heard these cries?((( She is hungry after breastfeeding, the milk is semi-transparent, although I eat well and drink plenty of warm liquids, but I need to supplement with formula, but I am already afraid to give her formula.
