Feels like AF is starting...

Jamie
Af is due today (14 dpo). I spotted once Monday (light pink), twice Tuesday (light brown). I've had some symptoms but nothing over-the-top. Bfn yesterday, didn't test today but it feels like AF cramps all morning! I know I'm not out til she shows, but has anyone ever had this & got their bfp? I'm torn between being realistic & not giving up 😕
