Toddler not sleeping! Help!

Sabrina🌸 • 🤵👰7/25/15 👧🏼12/6/13 👼2/21/15 👦3/26/16 👧6/27/18 I`m 26 and have 3 beautiful babies! Due with #4 September 2020
My daughter is 20 months and normally she had no issues with going to bed and staying there. But here since last Sunday she refuses to get in her bed and sleep. As soon as you put her in her bed she screams. Goes to the baby gate and screams. She has never slept with us ever. I'm not sure what's going on with her but I do know I need sleep and so does my husband. Last night I was up from 2-5 before she fell asleep. I had to get her and myself up at 6. Any advice with how I can make her want to be in her bed again
