ovulation questions

So before I had my son I could clearly identify when I ovulated, which was great! Like I had it narrowed down to a 48 hour window!  Now, I have ewcm for a lot longer... before it would be super heavy for two days, and rather light but there for a day before and a day after (before and after the heavy ewcm days).  Now... it's heavy for like 3 days! And I can't remember what my cervix position should be during ovulation....  I feel so out of touch with my own body now lol  I had used tracking of cm for years as a form of natural birth control, with great success... and then used that same tracking to get pregnant! Twice! ... but now that we are ttc again, I have it down to a week and that's about it... my ewcm seems to get heavy then light for a day then heavy again... it is sooo strange!
