Is it possible to ovulate if i didn’t get a positive ?

Vanessa

Last month was my first time trying opks, and it was clear when i got a positive on cycle day 16. My period was kinda off and long so i had trouble detection when cycle day 1 was. Not pregnant so tried again this month. No postive test yet but was cramping all day today and had some EWCM yesterday and the day before. Confused if i ovulated or not. Did i miss it?
