Implantation bleeding? Thoughts please

Lynnsey

Hello I had my cycle September 29th- October 5th the 6th my hubby and I had sex and he didn’t pull out I’m suppose to be getting my period on or around November 1st according to glow well lastnight October 15th I started getting brown blood like a darker brown not heavy but enough to need a panty liner it is still continuing this morning I read online you can bleed midcycle for ovulation which I’m suppose to be doing in the next few days so you think this is just ovulation bleeding or implantation blood? Any input ladies?
