Weak, achy arms and legs...

I thought I would see if any of you have had the same symptoms. It used to happen mainly in the evenings but now it is all day... I get shortness of breath, and a weak, achy feeling in my arms and legs... worse in my arms- in fact this feeling is constant through out the dayi but sometimes I also feel sort of anxious and almost like I will faint or fall asleep?!!
I have read about Supine Hypotension so am thinking this could be it? Some relief if I lean forward (even sitting up is worse) It happens if I am a passenger in a car... maybe its because I am sitting on a decline slightly?
Really not a fun feeling... Started at about 26 weeks.
