Don't know what to do! :(

My baby is 9 weeks old and is EBF but recently she isn't getting enough (always seems hungry afterwards) so I tried to give her a bottle but she won't take it! She screams as soon as it goes in her mouth and will not take it no matter what I do.

I've tried switching bottles, having other people feed her but she still refuses them. She will continue to cry because she's hungry and gets fussy at the breast since nothing is coming out.

I just don't know what to do it feels like she's starving herself! Any ideas to up my supply or get her to take the bottle?
