Pregnant? Is this implantation bleeding?

Alisha

Implantation bleeding? My period is due in the 23. This came out of me while getting my kids ready for bed. After I payed them down and checked I saw this. Since then it’s been about an hour and nothin has come out of me. I never had implantation bleeding with my previous 2 children so I’m not sure. I’ve been having a ton of pregnancy symptoms that lead me to believe I may be have baby #3 🤗 please help!
