Those who missed your period .. Have you tested?

Today is cycle day 38. My cycle is usually 29-30 days. But here’s the confusing part .. my ovulation for the past few mths are around day 16-17. This time round, it’s day 22( according to ovulation test kit) Hence, I predict period should come on day 36? ( 14 days after ovulation) Is that how it is? Scared to test and get a negative 🫠
