Not sleeping anymore

my baby is going on 3 months and she had started to sleep through the night but now for the past week she's been super restless. she will sleep until about 1am and then start waking up like every half hour throwing her arms and legs around, waving her head back and forth and fussing for her binky back. majority of the time she doesn't fall back asleep right away. instead she keeps her binky for like 10 min and then spits it out and cries for it again! At least once throughout the night she goes through a period that lasts an hour to an hour and half where she fusses for binky spits it out right away and then fusses for it back again. I've tried feeding her, not giving her the binky back after a few times of spitting it out, and I've got 3 different kinds of binkies on the way to try. She only uses her binky to go to sleep it's not an all the time thing and she takes 2 half hour naps early in the day and usually one hour nap later on in the evening. I'm exhausted and don't know what else to do!
