Decicion symptoms and conditions

Just want to survey everyone and ask for responses for the following 3 questions:

1. how long did you keep your Mirena and if you no longer have it, why did you have it removed?

2. how many of you had your thyroid checked? who's came back abnormal? what were the levels?

(I'm a medical student doing research on this one since I believe the levonorgestrel affects our thyroid hormone. My TSH was elevated to 5.2 which is considered "subclinical HYPOthyroidism". This was mid cycle when my natural progesterone AND synthetic progestin were cumulatively high. When I had it rechecked 6 weeks later (around my period when any natural progesterone level is gone) it was normalized at 1.5. So I think that the P+P screws up our thyroid and can throw us into a high TSH and "hypothyroid state". The opposite effect may be true during menstruation and we can become HYPERthyroid for a few days... hence the really bad anxiety?!)

3. where is everyone from? perhaps we can have support group meetings?
