Cramps while running at 5 weeks

Lisa

Hello Ladies! I’ve been an active runner for several years (average of 30 miles per week then reduced to 20 miles per week since late last year due to a knee injury). Some history...I had a miscarriage last year August. I went running this morning and started cramping about a mile into it. I stopped immediately because I was scared that something was wrong, especially given the miscarriage last year. Has this happened to anyone so early in their pregnancy? I would hate to stop running but I don’t want to jeopardize my pregnancy. My first appointment with my OBGYN isn’t until next month. Thanks!
