Milk dried up but toddler still wants it

I'm pregnant and my milk has completely dried up but my 17 month old will not sleep unless she nurses. We have tried everything to get her asleep and nothing works. She will scream and cry for hours and not sleep at all. My husband has even tried to get her asleep and it just doesn't happen. I'll even nurse her in her own bed so she gets used to sleeping there but it hasn't helped with weaning. I'm so exhausted and tired of being used as a pacifier. What can I do to get her asleep without needing the boob? Please help 😭😭
