When do you think I’ll get my positive OPK?

Question

opk?" /> 
I’m CD12 now, getting tons of thin creamy cm that’s slightly stretchy, getting thinner and stretchier by the day. Felt my cervix and it’s really low and open and this is my opk from today (bottom one, ones above are from CD10) 
When do you guys reckon I’ll ovulate? I’m still going to do opk just want your opinions 🥰
