Implantation?

Bri • 2 years TTC- 2 failed IVF, 2 miscarriages. MTHFR, Factor V, High FSH..starting another IVF in November
Just had literally a pin sized speck of blood after wiping. Nothing else since.  I am 9dpo today and have never experienced anything like that. Anyone have anything similar? I am hoping it was implantation!
