Cervical Mucus, Implantation, and Pregnancy

    Q: Can I find out if I am pregnant from my cervical mucus (CM)?


    A: You could be pregnant. But making the diagnosis of pregnancy from changes in the cervical mucus is too unreliable. You cannot make a pregnancy diagnosis from cervical changes alone. The typical stretchy and fertile cervical mucus (spinnbarkeit) develops under the influence of estrogen hormones. Estrogen hormones rise just before ovulation and decrease just after ovulation. At that time, CM becomes dry. About 7-10 days after ovulation, estrogen hormones normally rise again, and it is this second rise than can often give the appearance of fertile mucus again. That doesn't mean you are fertile again, because you don't ovulate again. There are no reliable enough changes of the cervical mucus to indicate when implantation or pregnancy has happened.
