I had that this month too it's somewhere In my journal I have to go find it

..........................................K here it is:
I did do some researching and found this for anyone else who might be experiencing this:
As long as the patient is not taking oral contraceptives (OCs), mid-cycle bleeding is most likely ovulation bleeding. This type of bleeding is predictable, occurring 10-16 days after the onset of the patient's last menses, light, and lasts 12-72 hours. It occurs in 10%-30% of women and is considered normal, resulting from a sudden surge in estrogen at ovulation that then drops, causing destabilization of the endometrium. The patient need only be reassured that this is a common occurrence and is simply the way her body responds to the hormonal changes associated with her menstrual cycle. Patients who find this normal problem a nuisance may benefit from short-term estrogen supplementation during the periovulatory phase.
*Realized you also wanted to know about implantation bleeding

implantation sometimes happens as early as 3dpo but normally about 6-10dpo so yes this could be implantation bleeding if you ovulated when you were supposed to.
I also read that it's a good sign of fertility
Hope this helps.

Let me know how it goes Good Luck!
