Are there specific changes of cervical mucus when pregnant so that I can diagnose my pregnancy from these changes?

A: Wouldn't it be great if we could diagnose a pregnancy just from changes in the cervical mucus? After all, the cervical mucus is a pretty good indicator when there are hormonal changes such as ovulation. But there are no typical changes of the cervical mucus when you become pregnant. It's not possible to know from checking the mucus whether you have become pregnant or not. You still have to wait until after you miss your menstrual period for that positive pregnancy test.
