So confused

Anyone experience anything like this? Had sex around ovulation, nausea and exhaustion soon after, spotting that was brownish day of period. Tests that looked somewhat positive (blue dye mostly and a pink or two that u could see if i tweaked it, or maybe just line eyes). Three days late, period arrives and lasts just over two days when usually it lasts five full days. Right after, now clear watery and egg white cm cd4.

Does any of this make sense or mean anything? Or just super weird cycle for no reason... 🤷🏻‍♀️🤷🏻‍♀️🤷🏻‍♀️
