Had clear, kinda stretchy cervical mucus last week and the next day it was white. was i ovulating?

Probably: Clear stretchy cervical mucous is an Estradiol effect and is most prominent when the estrogen level is at it's highest during the ovulation phase of a menstrual cycle. Women are most fertile when their mucous is clear and stretchy, the basis behind birth control using the billings method. If ttc, concentrating intercourse during these days is helpful. Avoid sex then if avoiding pregnancy.
