Implantation bleeding?????

So two apps predicted two different ovulation days. Glow said September 29th and Ovia said September 27th so I am either 10dpo or 12dpo. Since day 4/6 dpo I was feeling really weird and having a lot of pregnancy symptoms. I took a test yesterday and it was negative got up this morning and had some really light pink spotting when I wiped. Could implantation just be happening?????? AF is due on the 12/13. I’m keeping my fingers crossed because I really want to be pregnant 🙏🏽🤞🏾
