Need help I'm curious

Hey I'm new here and was wondering if anyone had an experience with implantation bleeding. I have two kids and never experienced it before. I spotted four days before my period which was day 10 after first day ovulating. My period was due on October 14. I spotted for three days and stopped. I am taking a test tmr for actual answer but can't stop stressing about it wondering if that was actually implantation bleeding. I am on day 36 since first day of last period.
