How easy is it to get pg with a copper coil?

[BlaDeBla]

I'm in my 40s and have all sorts of health problems. Just found out to my shock that I am pg. I've had a coil for years and years without any probs. How common is this?

My boss did and she only had it removed when the baby came out. Apprantly they couldnt located the coil during her whole pregnancy even though its clear on her scan.

My sister was born while a copper coil was being used. My friend's son was born while a mirena coil was being used. They never did find it.

Please don't scare me - I have a copper coil and my period is a couple of days late.
