Why the heck am I awake?

Rikki Dee
I'm used to getting lots of sleep! I'm only 6 weeks. Now I fall asleep around 11pm and wake up between 1-2am then I'm up til 4am. This pattern is really annoying. I'm super sleepy when I wake up (like I haven't rested much)! Hormones just out of wack? Is pregnancy insomnia a thing! I'm so tired but not sleepy! Uughhhh!!!! 😫
