Ovulation help?

Hi ladies. I have a question. I know some things about ovulation and CM but I have a question for you girls. I don’t clearly remember when I had AF I believe it was around the 9-12? I last about 3 days. There was no possible way it was after the 12th. I don’t quite know when my peak was or much about what the “Peak” means for TTC. Yesterday the 23rd my CM was watery, egg white and very heavy. I want to say about the 18th 19th it was creamy. My Cervical was soft and fully open. Today it is closing up and I am a bit more firm as well as my CM is sticky. Any insights would be appreciated. Thankyou. Baby dust!
