past week did not feel too well

This past week I did not work out as much.  I did not feel well.  I still do not know what was wrong with me.  For two days my stomach was really hurting.  I thought Mother Nature was announcing her arrival but it never came.  One day I was in bed the whole day with a heating pad.  I was never quite right all week.  I did exercise but I did not work out until Friday.  I guess I just needed to get back into the swing of things.
