I understand what you mean, I would have to say "yes"...Though each person is different. Mine tends to be very uncomfortable, but managable at times, then others it is unbearable. Most often the times that are the worst are when your mid cycle. The two weeks after and two weeks before kinda deal. At least its that way for me. Lately, things have gotten progressively worse and the pain gets harder and harder to "ignore".
I'm not sure about how others have their feelings, but mine say that it is notmal to come and go. It just depends on how unbearable it gets on day to day basis.
I agree with the above poster. My pain at times was just a twinge, a little reminder so to speak. Other times I thought I was going to pass out. It does vary I'm sure with each person, but from what I've read, it is quite common.
