I am 100% sure I ovulated because I test by opks (I know some will say that they are not 100% but I have been tracking my cycles by opks for a year and their accuracy is always right and accurate in my case).

Still, even though I ovulated I am still now 4days late. I tried 2 pregnancy tests (17 and 18DPO and resulted both in negative)

I will test again in a week time if AF doesn’t show up but still was curios if it’s possible for ovulation to occur but still no period shows up.

Any experiences or medical terms? Thank you!
