That's good advice, thanks. I just came off being sick too and haven't been able to exercise much because of first trimester fatigue/nausea and asthma issues...never really stopped exercising completely but definitely not in my pre-pregnancy shape. Guess I just was pushing a little too hard, though I was going slower than I would have pre-pregnancy, maybe not slow enough. Gonna definitely talk to my doc about it next week too.
That's happened to me even before I was pregnant. You must be working your body to much. Or your body didn't have enough water/sugar. I am a competitive swimmer so its not like I'm not used to a hard workout either. So just try to drink more water and work your body a little less until you see your doctor and see what they say.
It cleared up after I laid down for awhile, right now about an hour and a half later its gone. I have an OB appointment next week, but I'm only 13 weeks along.
I havn't, but it sounds like it could be blood cirrculation related.
