Confused

I am so confused. I ovulated October 12

Had sex 4 days (10/8) and 1 day (10/11) before ovulation and 1 day (1/13) after ovulation. Took a few pregnancy tests and nothing. I got what I thought was a normal period 3 days early on October 24, which lasted for 5 days. It stopped for 3 days and then I started spotting brown for the next 3 days, which brings me to today. I am still spotting brown. Took a pregnancy test today and it came back positive. Took another 2 and same thing. Line isn’t super dark but it is there on all 3. If I ignore what I thought was my period I would be 22 dpo. Had this happened to anyone else and what was the outcome?
