I had a copper coil fitted in 2012 after Ds2 was born. Has worked well for us until I smelled a rat this week and my worst fears were confirmed when I found out I was pregnant 
I am so annoyed at having to go through this and an inevitable termination - I would have so loved three in an ideal world but DH and I know that the financial and emotional burden would be too overwhelming, so as far as that's concerned, the decision has been made.
Has anyone else experienced or been through this?
