I have them on and off through the day and then they wake me up in the night. I am 6 weeks today and they seem to be slowing up For about a week though, I was not getting much sleep. They were far worse than AF Cramps, but the same type of pain. My Doc said it was ok, did a bladder infection test just in case and told me to call if there was any bleeding. So I think it is quite normal.
