Insomnia at 15 weeks

Mehgan
Almost 15 weeks pregnant with my first baby. For the last week or so, I have been experiencing insomnia. With already being so tired in the first place insomnia doesn't help. I work 40+ hours a week and running on 2 hours of sleep is not working. Has anyone else had this issue? Could any of you offer any advice that's helped you? Thanks in advance!
