Does anyone else get extremely nauseous during TWW????

I have no clue what causes it but every month during my 2 week wait I wake up extremely nauseous like I have to concentrate on breathing so I don’t puke it lasts for a few hours when ever I wake up , it’s extremely annoying too cause I know that I’m not pregnant and if I was it’s too early for morning sickness . I literally have to wait up earlier so I feel better by the time I need to go to work 🙄 does this happen to anyone else if so have you figured out what causes it and how to make it stop 👌
