Reflux baby?

My daughter had horrible reflux as a newborn & 8 months old I switched her to a soy based formula but now because of the shortage I had to switch her back to milk. She was doing fine for about a week but now it sounds like she’s having reflux ! I woke up bc I thought she was throwing up but once I turned on the lights there was nothing ! She’s 10 months old now. My daughter was slit feverish today I assumed it was over the teething but now the reflux ? Any advice or suggestions?
