5 month sleep help

My baby will be 5 months old on Friday. She is breasted every 3 hours during the day. Puts herself to sleep for naps and bedtime. Consistent bedtime routine but lately she wakes up every few hours during the night. Last night every hour!! We already went through a 6 week(😫) regression. I feed her 1-2 in the night so I know it’s not hunger. Sometimes when she wakes up she is just looking for her pacifier(trying to break that) but other times she is hysterical. Won’t take the pacifier, even after letting her cry for awhile shushing doesn’t help, putting my hand on her doesn’t help even if I resort to picking her up and rocking and calming her she just gets mad and screams more and arches her back. I have to nurse her to sleep to get her to stop. This is new she didn’t use to be like this. She’s fine during the day and for naps so I don’t know what it could be. Anyone have any relatable issues and could know what’s causing this?? Thank you!!
