Mirena and t4 levels

I had a baby in May.I had the mirena inserted in the beginning of August. I began having night sweats and noticing a lot of hair loss at the beginning of Sept. I went to my Ob/gyn who said it couldn't be the mirena causing the symptoms. So I thought that maybe I had a thyroid issue.(After my last pregnancy I had post-partum thyroiditis, which caused my hair to fall out and night sweats). I had my levels checked, and sure enough my t4 levels were high. So, now I am waiting for my t4 levels to go back to normal and hope that's what was causing my symptoms, not the mirena. I have also read that the mirena can cause thyroid problems, so who knows what is REALLY causing my symptoms. My most recent symptom is numbness and pain in my wrist/hand. I'm thinking it is possibly carpal tunnel syndrome which can be caused by hypothyroidism. If you just had a baby and are having the night sweats, hair loss, heart palpitations, weight gain etc.... I would recommend getting your thyroid checked.

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?
