The first thing that i would like to tell you about Mirena (which you might already be knowing) is that this is a hormonal intrauterine contraceptive device that releases levonorgestril (which is a progesterone derivative, not an estrogen derivative) in a low dose ( 20 micrograms per day).
Keeping the above in mind it is not possible for Mirena to cause the high levels of estrogens (total estrogens and estradiol) and other derangements in hormones that your blood tests are showing.
Therefore what i would recommend:
1. You should have a repeat of all the hormonal levels to make sure that this was not a laboratory error that has resulted in these results.
2. In addition to this i would also recommend that you have a screening routine pregnancy test as well, because sometimes patients using intrauterine devices can rarely have an ectopic pregnancy. So to be on the safe side i would like to rule this out as well.
3. If a repeat in the hormonal levels also show high levels, then you would require further testing, starting with an ultrasound of the abdomen and pelvis.
Hope that answers your question. However if there is anything else that you would like to know or anything that you would like to clarify please do not hesitate to ask me.
