Did you sleep regression get worse before it gets better?

Help! My LO started a major sleep regression at 3.5 months. She went from waking up 1 time around 4am to waking up 3-4 times a night. Now she’s a week shy of 5 months and the past week she’s been waking up every single hour and the only thing that will get her back to sleep is breastfeeding. I’m so tired and just hoping that she even goes back to the 3-4 times a night! Any advice or experience with your LO conquering the sleep regression?
