I'm a new runner (a few weeks in) and not due to start my period for another week. I had to stop a mile in today because I got a ghost cramps out of nowhere and REALLY wanted a vicodin. (It was contemplating-getting-in-the fetal-position-in-the-middle-of-the-trail type pain) I thought I started my period. Of course, as I was about half way limping back to my car (10 mins?) it passed and I felt completely fine. I then sprinted back to my car so I could make it home before the next one came. The thing is, it was a ghost cramp. I haven't started my period. What gives? I'm always well hydrated so I know it's not that.
In addition to going to the doctor, I just want to know: Is this normal? Can it be avoided? Should I start taking painkillers before I run?
