LMP - keep an eye out for increased swelling on that side that extends, heat and pain as that could mean that you have a DVT... if you are worried, a trip to the GP would be a good idea.
But swelling on one side can be the position of bubs blocking the blood supply and return...
Try and keep that leg elevated and lie on the opposite side to move bubba so that you can get better blood return.

completely off topic, but Hiridoid cream, incidentally, is also referred to as 'poor models facelift', if you put it on bags under eyes etc it will tighten the skin for a few hours - great for the sleep deprived pregnant woman or Mumma when she is trying to look not so sleep deprived
