Soy, coffee and Thyroid

Well, it turns out my TSH and Thyroid antibodies are at it again. Confusing as I have now been taking the Levothyroxine for 8 months now and they had dropped a few months back. TSH now seem to be outside the normal range confirm I have a propensity to primary hypothyroidism. Annoyed as my levels need to be 2 or lower to be safe for pregnancy as anything above that heightens my chance of miscarriage and preterm labour not to mention risks with fetal brain development. 

January: TSH 3.8 mlU/L

April: TSH 1.2 mlU/L

August: TSH 4.67 mlU/L

Also Antibodies results show they are also very strong, 90-100% of cases of Hashimotos Thyroiditis and Graves Disease show antibodies. Less than 10% of normal individuals have thyroid antibodies.

January: Anti-Tg (thyroglobulin) 241 mlU/L

August: Anti-Tg (thyroglobulin)  537 mlU/L

January: Anti-TPO (thyroid peroxidase) 244 mlU/L

August: Anti-TPO (thyroid peroxidase) 871 mlU/L

It turns out that consumption of soy products, so soy milk and coffee may be causing issues with my body's ability to absorb the thyroid medication so I've emailed my nurse and GP to see if I have to stop my morning coffee...nooooo! Its the only thing I'm allowed these days haha. So, all in all we may have found a very possible cause of current fertility issues, I may be seeing the thyroid specialist after all. Will wait and see.

Right, heard from my GP and it turns out she never got my blood results but has managed to track them down. Thyroid TSH levels definitely up due to antibodies so shes up'd my Levothyroxine meds to 100 mcg Monday-Friday and 50 mcg on the weekends. Have to do another set of bloods in 6 to 8 weeks to check again. Means we cant TTC while my levels are up so more waiting. Should have MRI done by then.
