Wierd pins and needles

I've been meaning to say this for days. I can only assume it's the result of the weakened veins & progesterone or *something*, but I've been getting pins and needles in my arms / hands if I lay in slightly awkward positions, incredibly easily.

Did anyone else ever get this or is it just my strange-o physiology?

Am not necessarily feeling "better" as such - a bit weak from sleep actually, but haven't been feeling worse - which can only be a good thing.
