Thyroid

We've been trying to conceive  for about eight months now after a miscarriage after 11 weeks. I had my hormones checked last month since I still have not gotten pregnant and my thyroid and prolactin levels are high, I was put on a prescription thyroid medication and I'm waiting to find out if my levels have normalized. Anyone else been diagnosed with hypothyroidism and/or hyperprolactemia and how long after being diagnosed it take you to get pregnant?
