Mucus Before Menses Early Pregnancy Cervical Fluid?

Early pregnancy cervical fluid? - mucus before menses

This is TMI, but need to know. With my last pregnancy I had a lot of cervical mucus (CM) of ovulation in the rules. That's how I knew I had before, because the pregnancy is adopted before menstruation CM was that the dryer. I'm hoping preg again ... I have only 3 weeks, menstruation is expected within a week, so can not test it yet. However, CM has not dry when they came to a positive pregnancy test? Only one hope, thank you!
