Opinion...advise...thoughts....anything really :)

So here's my story.... 11 DPO I got a faint positive or at least I thought any ways maybe Evap? (Pic below) ... Then 12 DPO Neg  ...13 DPO blood came back 0.... I figured chemical Dr said unsure but that wasn't pregnant Tuesday the 26th! I accepted that and got my period one day late....no big deal right... Well day one was fairly light with much heavier cramping than normal ...day two still light.... Yesterday dark brownish red spotting only a few drops.... I started to get very confused.... Today brown spotting only when I wipe with very low abdominal cramping! I'm really confused as I have normal 4-5 day periods with very minimal RED spotting the last day! Any thoughts from you ladies on what's going on or anyone been through this have any words of advise would be so appreciated!!! After two years of trying I've never experienced anything like this before and I'm confused as hell 😶😶😶
