Preemie Fighting sleep for hours HELP

Hi ladies

I’m worried is it normal for baby to fight sleep for over 5 hours. My baby is 7 weeks 3 adjusted. We have tried everything from feeding, burping, rocking, white noise, go for walks, turning the light out,swaddling and she won’t sleep. None stop crying.

Yesterday she fought sleep from 3pm till 10:40 pm. None stop fussing. There’s nothing wrong that we can find no fever,diapers change fine, eating fine if anything over eating,burping fine.

I don’t know what to do
