Well, it can happen. When did you have your tubes tied? Now a days, they actually burn them (sounds awful, I know) to prevent them from repairing themselves. If they are just "tied" they can and do come "untied". Be very careful, it's more likely that if you are pregnant, you could have an ectopic pregnancy ( more likely in patients who've had tubals). Take a HPT, and if it's positive, or you don't start you period within the month (of October) go see your Doc ASAP.
