Sleep regression?

I’m almost positive it’s the 8 month sleep regression because she use to sleep good. But some nights well get her to bed and she’ll be so tired but an hour later she wakes up wide awake and refuses to go back down until after midnight or she’ll wake up at 4;30 thinking it’s time to get up but be tired still and again 2 or so hours later she’ll be ready to sleep for a long time. She’s also waking up 4 times a night. I’m just so tired i wasn’t even this tired when she was a newborn 😓😓 she’s also been teething for awhile now her teeth just look like they’re about to poke through but hasn’t and I think that’s adding to it. Is anyone else going through something similar?
