What do you think the chances of me being pregnant is?

Are you old enough for menopause? Your husband never going back to the doctor was very irresponsible. They need to check the sperm count to be sure the procedure worked. Since you haven't become pregnant in the past 2 years I'm guessing that it must have worked though. The only way to know if you're pregnant is by taking a test.....or waiting until the baby pops out.
