BF baby

I breast feed and give one bottle a day of formula to my baby. Today my LO has been hysterical and when I’ve tried to feed her she’s refused my boob. I didn’t know what else to do so I tried a bottle of breast milk and she drank it, it was only 60ml so I tried her on the breast after and she was hysterical again and refused so I’ve had to give her formula again in a bottle now she’s asleep. This was both breast and even with me squirting some breast milk into her mouth. Has anyone had this?! Is she likely to go back to my breast again? It was awful 😢
