I’m on my third merina coil. I had one prior to having kids, then another after my first and another after my second. The major pro (apart from preventing pregnancy) is the extremely light (almost no) periods as I had very heavy ones before. However, every month I have the most horrific itching - doctor suspects it’s thrush. It happens every month and it’s unbearable. I think I have two options - get it out and just use condoms or face the unknown and get an implant. I had one about 15 years ago so I don’t know how I’d react. I really don’t want any more kids so have to be careful.
