Missed period so when will I ovulate?

My periods have been like clockwork for the last 7 months since coming off the pill, literally to the exact day. Apart from this month...I’m 12 days late - sadly I’m not pregnant 😔 (absolutely gutted).

What does this mean now for ovulation and will I still expect my period any day now or will it skip a month essentially?

Any help appreciated 🙏
