Just starting week 4, so proud of myself -until I did this I honestly don't think I have run for over a minute.
However, last couple of sessions when I get off the treadmill I have what can only be described as really bad period pain (and it's not the obvious cause...). It's only when I stop, and it goes of it's own accord after about 5-10 minutes but it is that dull ache around the bottom of your tummy where you just want to curl in the fetal position (to stretch the muscle out and ease it, rather than out of depression and agony) until it goes away.
Any ideas on what it is, what's causing it and how I can sort it out. It's a darn inconvenience.
