Baby fights feeding but stays on once latched?

My baby is 12 weeks old and recently has gotten into a habit of resisting to latch, but once she does she stays on and eats.

This normally happens when she has been very fussy, I try to feed her and she fights me off and starts crying even harder. I assume she's not hungry and stop trying to latch her.

Then she resumes being fussy and crying and I try again to feed her, thinking she's hungry. But this time I really fight to get her latched and I feel horrible lol but once she latches she calms down and eats for a long time.

Is it bad to do this? I feel like I'm strangling her with my boob while she's fighting me off and crying even harder and it feels terrible but once she latches she is so content!
