Implantation bleeding?

Hello ladies, so I'm back on the app after my second chemical pregnancy. I got a positive pregnancy test August 20th and found out it was a CP August 25th for the second time. I decided to stop trying for awhile because of the emotional toll ttc was taking on me so my period was due September 26th but didn't show up however when I wiped yesterday there's a very light brown discharge I also wiped today and the same thing happened. Any chance this could be implantation bleeding??? Thanks in advance!
