It should be ok while youre ttc... its a hard one. If youre charting and can get in early and find out that youre utd then either change or not take it. Have you stopped taking it before? If so you need to think about what happens to you when you do? Do you quickly relapse/have an episode? Or is that something that happens gradually>? Definately one to take up with your health care provider.... and have a chat to your dh about it too.
