Hi, I am not sure what my levels were but after DP and myself were TTC for 6 months our doc did some tests and my thyroid was broken - so to speak - Hashimotos Thyroiditis! Not sure if that is what you have but once my levels were regulated by 100mg of Thyroxine we fell pregnant the next month! Even though I have to take the meds for the rest of my life - there are worse things! Now pregnant my medication has been increased but I havent had any other problems.
