Ovulation on 17th May/Cd11?

Would you agree that I ovulated on 17th/CD11?

I had EWCM and a pos opk a few days before.

I am curious because I had a drop in temp on May 19th, I’m relatively new to temping so need a little help.

My cycles have become shorter, which is why Glow still thinks my fertile window is later in the month.
