Marina coil side effects


@Dr_Paula I have had my 2nd iud for 2 years now . I have always suffered from bad headaches but since this coil they have become unbearable to I even go blind in one eye. I have been having severe labour like cramps randomly and also had some jelly like bleeding. I can also now only feel one coil string. Could all this be down to my second coil or somthing else ?
