Hypothyroidism and TTC

Kirsten
I am beyond nervous. A few weeks ago I was diagnosed with hypothyroidism. My TSH levels were 8.25. I was started on 50 of synthroid. 
​My mother was diagnosed with it at age 20 and then diagnosed with thyroid cancer at age 25. I go in on the 13th for an ultra sound on my thyroid.
​My husband and I have been TTC for almost 2 years now so I'm hoping the medication will help with that. I am 10 days late as well. Could the medication affect my cycle?
