Is this IB?

Hi ladies so I’ve never had anything like this! I am 11 or 12dpo today. I’ve had pregnancy symptoms since 4DPO. I just don’t feel myself. I’ve had deep full and sharp cramping all day in middle lower abdomen where uterus is and on right side super sharp jabs here and there on pelvic bone area. So I wiped and I found these little specks of pink! If I didn’t look closely I wouldn’t have seen. I zoomed in. They’re no larger than a pin needle! I brightened it a bit and I also saw some light brown tinge. I checked my cervix with finger an Q tip and saw no blood. Wiped again nothing. Period due in 3 days. I never had this before! Is it too late for Implantation bleeding? Anyone else experience this and resulted in BFP? Plesee help XX
