Period

The app says I should have ovulated on the second but I took an ovulation test and it was negative I took one he 9th close to midnight and it was very obvious it was positive. And I know that you period starts 12-16 days after ovulation peak. So if hard true wouldn’t that only make me going on 2 weeks late tomorrow instead of 3 weeks late?

I still have no signs of period but yesterday had some breast pain and my lower back was hurting
