You could still ov Hun, you are under alot of stress coming off your medication. I know that stress can effect ovulation! I'm usually a straight forward 28 day cycle, ov on day 15/16. Do you think that happened last month?
Nope I was 3days late for no aparent reason! I felt like you do, was stressed and thought it just wasn't gonna happen.
Keep testing Hun you could still be due to ov, I really hope you do xx
