Have an appointment for Mirena insertion on Friday, but struggling to decide whether to go ahead with it. What puts me off is my experience of the Progesterone Only Pill. I don’t think I’ve ever tried it for longer than about 3-4 months but I had the impression it affected my mood, and I disliked the breast tenderness & irregular bleeding. I know Mirena is a lower dose of progesterone, but I’m worried how it will affect me. I’m a migraine sufferer so can’t take the combined pill. Not keen on copper coil as my periods are heavy anyway. Some people also think migraines improve with Mirena. How have you found Mirena, if you’ve had one?
