Hello Kazza48
I am wondering why your doctor gave you the mini pill instead of HRT when you already have the Mirena coil? I presume the coil is not yet due for renewal as the hormones run out after a few years? Did you have menopausal symptoms that you wanted HRT for?
With a coil it's often difficult to tell where you are in menopause because it can stop periods completely giving you a false sense of your last period - ie it would be earlier than if you didn't have a coil. Did you have menopausal symptoms eg flushes and sweats? The mini pill will do nothing for these and in fact I would suggest if your Mirena is still giving out progestogen then you are having far too much progestogen. This can cause over-thinning of the womb lining ( atrophy of the endometrium) which can cause ulceration and irregular bleeding.
If you are getting other menopausal symptoms then I would stop the mini pill if the coil suits you and ask for some oestrogen only HRT - either tablet, patch or gel and this should help your symptoms and stop the bleeding.
Alternatively if the coil is more than four years old the bleeding could be because it has stopped working and you need to renew it (as well as stop the mini pill). I am wondering if you were given the mini pill because you were getting bleeding on the Mirena?
If you tell us a bit more then hopefully we can help
