Nursing to bottle 😞

I need help getting my daughter to get on the bottle. She’s been exclusively breastfed and she’s 3MO. I’m starting school in less than a month and I have quite a bit of my milk in the freezer but she will not take the bottle 😞 so I’m wasting my milk (I no longer pump I produce enough just to nurse) because I end up having to just feed her myself. Any advice? I’ve tried putting the bottle through my nursing bra and she still knows it’s different. I’ve tried both the Avent and Dr. brown bottle. Thank you!
