At the top of the page there are some options, including "Watched Topics" and "Topic Log" on the bottom row.
However, neither would help in this situation.
Watched Topics - a thread will only show if someone else posted to the thread AFTER you last viewed it. As it was several weeks ago, it's probably way back and not being viewed. It's totally possible that in a month or two from now someone will find it and post to it, which will make it show up again next time you click Watched Topics.
Topic Log - is a list of the topics you recently viewed. But it only lists back a certain number of topics (I'm not sure of the exact amount, but it certainly isn't going back several weeks ;-) ) , and if you've logged off, it will clear out everything for that session. And sometimes it clears it out within a session.
HTH.
