Morning. I am nearly 5 weeks pregnant and for the last week I have had barely any sleep due to horrendously vivid nightmares. I always wake up after the nightmares with a super fast heart rate, shaky hands and I'm also usually very sweaty. Has anybody experienced this before? Is there anything I can do to try and get a better night's sleep? I am exhausted, and the nightmare usually plays on my mind throughout the day. Thank you!
