3rd trimester insomnia ??

so i’m 36 weeks , and for the past few days .. i haven’t been sleeping at all through the night , i’d go to sleep between 8-11pm then wake up at like 2am and can’t fall back to sleep , i’ve been sleeping fine throughout my whole pregnancy until now , and i’ve had no problem with getting comfy enough to fall asleep so idk what this is ?? i wish i can sleep so i can be well rested for labor and my new baby , is my body getting ready for labor or something , sleep for me is non existent 😭😭😭 i don’t want to take anything for sleep 🙅🏽‍♀️🙅🏽‍♀️ is there anyone else having the same issue as me ? is this normal at this stage in my pregnancy ??? it’s literally 4:46am and i’m wide awake , been like this for maybe almost a week
