Cycle tracking help!

Hey, so I’ve just started trying to track my cycle. This is all new to me, had read about tracking by cervical mucus.. this is what my calendar is like on the app. However on Monday I noticed very slippery, clear, stretchy cervical mucus. This lasted for a while then yesterday it was white and creamy. What do these typically mean? Can anyone help what these are signs of? And whether either is a sign of ovulation?🤞🏼
