Im also 6 weeks and feeling the same way. I can take a power nap during the day but at night it takes sometimes 2 3 hours to fall asleep. So its got to be somewhat normal.
Im 33week and can sleep either. My body and mind are just restless im tired but just can't get any sleep at all was up all nyt.
I'm having the same issue.... it started about the same week for me too.... I'm still having issues at 11 weeks. My doctor says benadryl is ok....that usually puts me to sleep, but I still haven't tried it... I was told a doctor should be able to suggest something just for sleeping
