New to tracking ovulation

So I am new to <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> tracking cuz we recently decided to TTC. 
I should've went out a got ovulation tests but I think it's kinda late for that this time. 
So my question is..... I had lots of clear stretchy discharge for the last 2 days and today it's lots of creamy thick discharge. Does anyone know if that's a sign of ovulation or did I already ovulate?? 
Thanks for my help!
