Cervical mucus..

Faith

Hey ladies, any of you ever get a kinda heavy flow of thickish milky white cm right before a positive test ? Im supposed to get my period in a few days but we dtd a lot over the past couple months up until about 2 weeks ago and suddenly right before my expected period I'm getting this type of cm which doesn't usually happen before my periods so I'm wondering if anyone got this type right before a positive prego test?
