He knocked my af on twice?!?!

I have irregular AFs. Like I had one Jan-March. Then a normal in July and skipped Aug. So in the middle of Sept. We bd and I woke up to AF it lasted 11 days somewhat long and heavy. During ovulation according to glow we bd every other day. Then on the 18th of Oct. we bd and right after I spotted. This lasted on and off very light when I wipe til Oct 21st. My af was due on the 23rd and did not show. Today still nothing!?! What do you ladies think is going on?
