Cm question...confused

So i did an ovulation test on Tuesday and it was positive same yesterday.

Anyway yesterday i had very watery but white-ish cm, looked and felt like milk (sorry for tmi) so wasnt stretchy. And today i have checked and its very tacky. I thought usually cm should be like ewcm.

Is it possible to conceive with milky watery cm??

Also yesterday was a tiny spot of brown blood on underwear
