I am having the same problem and this is my second pregnancy and my first wasn't near nothing like this ,y arms and wrist hurt, but I have been reading that women develop carpul (check spelling) tunnel syndrome and our hormones are so out of control that they cause body aches. Go to the doctor and explain your aches because I am.

a fetus takes up alot of the calcuim in a womans body.
some pregnant women get chipped or cracked teeth because of the amount of calcuim that a fetus takes.
and as we all know, calcium helps build strong bones, so you might be lacking calcuim or something else that is making your bodies ache.
talk to your doctor about this to see if you can take anything to help.
