Pregnant, milk drying up, baby hates formula

I am 11 weeks pregnant and until now I have EBF my almost 7 month old. I have began to notice a drop in my supply and I can tell my milk is beginning to dry up. My daughter has always refused a pacifier and every bottle we have tried she hasn’t taken to. We just started trying to give her Gerber Gentle formula and she won’t even let it touch her lips before she refuses to drink it. We’ve tried other brands and using a sippy cup and she won’t take any of them. What are we supposed to do? My husband and I don’t want her to starve but are lost at what we can try or give her to feed her. We know she is too young for cows milk and she needs formula for the nutrients but what can we do?!
