help!?! When did I ovulate?

Nicole
Hi guys. I am trying to figure out my o date to see if I am actually late or not. FF says CD15 without opk and on FAM. FF say CD14 with opk on Advanced. FF says CD20 without opk on Advanced and Glow says CD14 with opk and CD17 without. Pregnancy tests are negative. My LP is 12 days. No AF....
