Cramping, how do you know?

Ali

Hi all! This is my second month really paying attention to my symptoms of ovulation. I am on CD 11 now and am having random bouts of intense cramps and some pressure on my right ovary/tube area. I am also very dizzy, have had lots of heartburn and randomly nauseous. This has been going on for 3 days now.

My OPK comes back low, but glow says I should be ovulating in 5 days.

Is this normal? Or does anyone have any experience with this type of symptoms before ovulation?
