Did I miss my O?? help!!

dc

I am so confused if I O or not yet. I’ve been taking my temp and using OPK and they have all been “low”. But this morning I woke up with no more CM and the last couple days I there has been white milky but stretchy now, Now nothing I even caused my finger to check. Sorry TMI. Here is my chart so far. Last month I O CD17 and ended in a chemical. Did I O already or I am still too early? I do have cramps and tjnges on my right side.
