Q&A: Where does cervical mucus come from and what should it look like?
Does cervical mucus come from the cervical canal? Is it normal for it to be milky-white at ovulation rather than clear?
Cervical mucus does indeed come from the cervical canal. As an egg is developing, the ovaries produce more estrogen. This estrogen causes the cervical mucus to change as ovulation gets closer. The mucus should become thinner, stretchier, and clearer. If you have milky white mucus at the time of ovulation, then there may be a problem. You may not actually be ovulating or your timing may be off. Either way, this is a reason to be checked out by your fertility specialist.
