Still confusing

As stated in my last post about my period being from the 9 through the 13 and stopping but on the 23 I had started spotting again and the spotting turn into bright red heavy bleeding that lasted 5 days again. I did have sex the 27,28, and 29. I took an ovulation test the 28 and it was positive I will attach the pic but yesterday I got a even more positive with the test line even being more stronger so I’m not actually sure if I ovulated yesterday or the 28 and was the 23 through the 27 really a period
