11 days late!

My period is 11 days late. I had a stressful breakup for 2 weeks. We got back together, later on. Anyway, I have made some changes in my routine like waking up early and doing high intensity exercises for 1 hour. Also, three weeks ago I had protected sex and the guy jizzed outside of me. So, pretty much safe there, I guess.

Also, the day I was supposed to get my periods, I saw dark blood with my other fluids which usually secrete while ovulating. I don't know if I had a delayed ovulation, or what. The blood was not a lot. But it happened the day I was to get my periods and so I put a cup on. But it wasn't my period and I still haven't gotten it. I saw the blood for two days but it wasn't even enough to stain my panties. It would just come out with other fluids.

P.S. been having irregular/late periods ever since the lockdown happened!

What to do? Did I just miss an ovulation because I don't feel heavy the way I do before a period. Or did I just conceive supernaturally, with my thigh?
