Nursing Strike 😫🥺

My daughter has been on a nursing strike (yes this is a real thing) I Googled it after the lactation consultant said its most likely whats happening. I had started the mini pill and and every since I started it she just refused to nurse! She would turn her head away and scream! Or scratch at me pushing my breast away. This lasted 4 days and had to give her pumped/formula milk. I've finally gotten her to nurse again but it scares me death it'll happen again. I cried for those 4 days because I felt so rejected 😞 and wasn't sure what I had done. Has anyone went through a nursing strike before?
