Evening everyone. I have a copper coil and have had it for 5 years. For the last 6 months I've been experiencing cramping and spotting after exercise. I run marathons so I am used to intense training, it's often worse when my sessions are tough. I have been to the GP who has referred me for a scan and put me on the pill in case the coil isn't working (on the face of it it still appears to be in place). I've had a clear smear. I'm not pregnant. It's ONLY when I exercise. I am starting to wonder if it's the coil. Has anyone heard of this of experienced it? Thank you!
