I’ve been using a copper coil for years. Prior to having my children and again having had all my children. I’m now 43 years and I’ve noticed my periods have got heavier, not sure if it’s because I’ve had four children or an age thing. I’m considering having the coil changed to a marina coil but a little concerned about weight gain and also in the unlikely event of falling pregnant, not knowing etc. Any thoughts, experiences, tips and knowledge would be gratefully received. Thank you in advance ladies x
