Undo System Restore Option Not Available

Hello!

So back on Sep. 12, 2013 I did a system restore to about 6PM on the 11th. It is now October 3 and I am not seeing the option to undo the system restore. Is it because I waited too long?

I have Windows 7 Home Premium.

Also, the dates/times that I have listed in System Restore keep getting fewer and fewer. Is there a way to locate old System Restore points?

Thanks so much!
