No sleep

My little one is just over 19 weeks so we should be out of the sleep regression however the past 3 days she's been up all night not even just to eat just wide awake and won't be set down. I've tried everything and we've made sure she's not taking long or too many naps during the day. I'm breastfeeding and working full time I don't know how much longer I can keep this up. Normally when I'd pull her into bed with me cuz she couldn't sleep she would nurse and sleep like a rock now she just wiggles abd kicks and bats her arms around like crazy. Please help
