YES! I got them a few times during the night when pregnant. Id wake up either in the worst pain or when i got up to go to the bathroom i would get the worst cramps up my leg.. trying to pull my foot back as you do did nothing and i just had to bear the pain. Ive been talk its possibly due to your body needing more salt. Bub's is draining you from all the goodness you have so you may need some extra.
