Not done with sleep regression?

My almost 4 month baby had a few nights when she woke up every hour. I knew it was the sleep regression so I just waited until it got better and it did, she has been sleeping better for about a week and a half. Now, suddenly, she doesn’t want to be put down. She is whiny and is like going to sleep hurts. We tried rocking her, cluster feeding,Swaddle, not swaddle, and once she falls asleep she’s OK but going to sleep has been tough. She also is whiny when she’s awake and is eating every two hours. Is this also sleep regression? Anyone in the same Situation?
