Sleep regression? Help!

My baby is 8 weeks old and EBF. She had been consistently sleeping for 5-6 hours straight at night since she was 4 weeks old. The past 3 nights she's been waking up every 2-3 hours. Our bedtime routine hasn't changed at all and I'm starting to lose it. The only way she'll sleep longer is if she's in bed with us, but I don't sleep when she's in our bed and I really don't like doing it since she's so little. Has anyone else dealt with this? I didn't think sleep regression normally hit until closer to 4 months.

I've tried lavender lotion and not letting her nap too close to normal bedtime. We swaddle and have white noise all night and use a pacifier but she normally won't use it at night to sleep. She hates baths so I don't know if doing baths would be an option, also I don't want to do baths every night because of her sensitive skin.
