Can someone plz help I’m confused lol

1.) When after do you ovulate after making egg white cm?

2.) if you have sex and check your cm 8-9 hours later is it sperm or is it cm?

3.) how high is your chances of conceiving if your having sex every other day?

4.) if I’m on a night schedule 3pm-8am when do I need to take opks?

5.) Best opk test to buy?

6.) How effective is preseed?

7.) can opks not pick up a surge even with testing twice daily?

Thank y’all in advance. 💗
