TTC with thyroid issue

I am TTC for the last year. I would take the ovulation tests and I would be late and have symptoms but never a positive test, then get my period. So time went on and then I started to gain alot of weight out of no where come to find out I have an underactive thyroid. The doctor said this is one reason why I haven't gotten pregnant yet. So they said my levels are normal now with the medicine. It is really crazy how this issue affects so much of your body functions. I am still trying to stay positive with my issue and everyone around me being pregnant it is very hard to stay positive. I just hopes it happens soon for me and anyone that is going through this too... Is anyone dealing with the same situation I am?
