After How Many Days After Ovulation Does One Start Their Period?

How many days after ovulation does one start their period? - after

In the past month I have ovulation kit at the time of my ovulation. I started my period 14 days after ovulation. This month again I have the ovulation kit. I just ovulate 20-21 days after the beginning of my time (that's the) same as last month. Now, however, is 18 days after ovulation and have not started my period. Abdominal pain, and I think I'll start my time at any time. I do not want to be too optimistic Pegna. But can anyone tell me what time to start my ovulation period. If it remains constant from month to month? Other symptoms I have tenderness in my breasts and I feel a little inflated.
