Hey, I've got the copper coil and have had it for about a year now. It made my periods much heavier and mine are always regular, ever since they started. I've missed one this month and I had what looked like implantation bleeding about 3 weeks ago. Still no period, but also no positive preg test. I'm not sure what's happening. Anyone else in same boat or had similar experience? Just strange because I've never missed a period except from being preg with my two kids. Thanks xx
