Is it possible to ovulate on CD 10 and 11?? I have a 3 day period and a 30 day cycle, I don't use opks although I do normally have headaches upon waking up, ewcm, and cramping around ovulation! This was my cm on CD 10 and 11,

Since it has went to a creamy, lotiony discharge that is white. I just figured If I ovulate on CD 10 then wouldn't I have shorter than a 30 day cycle?! I'm way new to this! any advice is appreciated, thank you 💖😊
