I'm so new to this pregnancy stuff. This is my first baby and according to my lmp I'm 5 weeks. I know I found out early. I now have night sweats and my legs hurt making it hard to sleep.
I found out when I was 5 weeks too. Best advice I got:
Get a body pillow, or a pregnancy pillow.
Have a bucket handy in case of nausea onset.
Don't eat super greasy food right before going to bed. (Trust me. You'll either end up with heartburn or nausea in the AM)
Heated blanket for any pain (use caution with them while pregnant though)
EPSOM SALT BATHS ARE AMAZING! Especially scented ones (which you can customize your scent you like)
& I can't think of anything else off the top of my head.
