I am 4 weeks and have some of the same symptoms :
-Every time I lay down I fall asleep. Sometimes I am half asleep but cannot get up - I told my husband the other night, 'I can hear you, I just feel like I am paralyzed, so keep talking.'
-I have been having wild dreams, but I actually like this - so vivid and clear.
-I have had cramping, I figure this is baby number three and that is normal, plus my last baby did a number on me and I had to basically put my uterus...
