Another month no baby :(

Hello my husband and I have two kids..and have been looking for numer three for over a year..I am hipothyroid found out on march started taking medication on july because supposivley being hipothyroid reduces level of pregnancy so with med I should be back on track ovulating as I should..but since july nothing has happened yet..:( very disappointed. My husband takes depression medication as well..and now I think that might have something to do as well with me not getting pregnant. So..trying to see what we can do to help conceive. Thanks for reading! :)
