Muscle fatigue

Thought I would run this past you ladies. The last few days after just a few seconds of doing something I experience extreme muscle fatigue, like I've been working out or something. It happens to my legs after I walk a very short distance- like from the living room to the bathroom (no stairs), and my legs get that tired, short on oxygen feeling. It happens a lot with my arms. I simply raise them to do anything and they feel tired. Is this a pregnancy thing or should I be more concerned? I don't remember this with my daughter. Just wondering if anyone else had experienced this. I am nearing 32 weeks with twins. Thanks!

I have no idea what it could be...but it'd definitely be something worth mentioning to the dr.  Would it be possible that when you're standing, one of the babies is 'sitting' on a vein/artery slowing down the blood circulation, and thus the oxegyn supply to your legs?  Or that maybe there's just so much blood going to them that the rest of your body's not getting s sufficient amount?  How do your finger and toe nails look when this is happening? 

It could be nothing...or it could be something important the dr needs to know.  Mention it to him/her and see what they say.
