I've never understood why she believes she's barren just because Mirri told her so. Mirri had all the reasons in the world to lie just to make Dany miserable.
*shrug* Well, prophecies are as common in Dany's life as snow is on the Wall. She believes in a Maegi's words, and, despite what she claims, at times she really is
a young girl who knows nothing. I rather suspect that if she were alive today, she'd be one of those people that goes to psychics and then makes future plans based on the predictions she heard (course, in ASOIAF, prophecies have some basis - still, she doesn't really question the existence of Quaithe, which is a little disconcerting).
As for the question at hand. I don't think the thought's even crossed her mind. It's brought up in Meereen when Hizdahr's family wants to make sure she's fertile, but she doesn't consider that Westeros would want the same thing of their queen. If she really believes she's barren, she should at least recognize that the line ends with her, no matter how
glorious her return to Westeros is. The line could still theoretically continue through the male Targaryens running around (pretenders, secret, or even bastards like Aurane that could theoretically be legitimized), but Dany doesn't really know about any of them.
She hasn't told anyone about it so she must recognize that it's probably an issue, but this seems to be another instance of her willing blindness ("If I look back, I am lost" is a pretty poor life philosophy - has she never
heard of learning from her mistakes?). If someone like, say, Barristan knew about this little hiccup, he'd probably tell her that the lack of an heir would just create another succession crisis when she dies and her taking the throne would only forestall it. Even if she's a perfect queen who reigns through the long night and manages to keep Westeros entirely happy, fed, and at peace, there's no way to avoid that little dilemma.
Wow, that was a lot longer than I intended...
