I’ve been stressed a lot, a sharp pain when I pee sometimes around my ovary or it feels a bit tender for an hour. I am 9 days late on my period, no cramping. And I took a test that stated negative 2 days ago. I’ve had my period for at least 12 years and every month it’s pretty much late ( so irregular) but it’s rare that it’s past 7 days late. I had cysts when I was a teenager but that was 8 odd years ago. Any idea on what could be going on?
