CD29....weird stuff, help?

Gabrielle • PCOS victim. currently CD10 & day 10 of metformin :)
So I took a test when I was CD26 and it was negative but it was about 4-5 days before AF was suppose to show so no biggie I expected it...
​Well now I am CD29 and I thought I was starting AF but low and behold it was like I was drenched in CM is this a good thing? Any insight would be nice.... It's Wednesday and I'll be testing this Monday!!!
