HELP!! 4 month regression!!!

My girl will be 4 months on the 1ith and the last few days have been hell! She wont nal long during the day so shes always tired and will scream at the boob when i try to feed her she is only content with her soother most times. She will sleep all night but im starting to get worried about the lack of sleep during the day and the trouble feeding. Anyone experience this?
