Ovulation bleeding or implantation bleeding

October 2019 I got my period the 29th-1st

November of 2019 I got my period the 20th-24th and my cycles are 29day according to my eve app.

December it says I’m supposed to get my period the 21st-26th. I was ovulating through the 2nd-8th. But I started having light bleeding/spotting the 4th-6th (light in color the first couple days then the last day it was a little bit of a darker red)

I am currently pregnant now and my due date is September 5th I am currently 9wks pregnant and a G/A 10wks. I looked up online conception calculator and they all say I was ovulating in the 5th of December but that’s when I was spotting. Did intercourses from before the bleeding cause pregnancy or after the bleeding? In other words was that implantation bleeding or spotting.
