Cm question?

AF is due 1/22 according to my calculations and 1/23 according to glow. Currently on cd23 and approximately 8-9 dpo according to my observations and glow. My cm has been increasing the last few days and i check several times a day. Throughout the day when I check, sometimes it is creamy and whitish and sometimes it is watery and sometimes it is a mix and it varies throughout each day. Usually I don't have quite as much cm before AF and I know it's not the best way to look for pregnancy, but I just wonder does anyone else get these kind of results either on a regular basis or before they got their BFP
