Help!?

So my period was supposed to start on the 19th, and it didn’t happen instead I’ve had on and off spotting and it’s not red, it’s like pink brown colour, I had sex on the 11th of August but I actually ended up ovulating late going of cm and light cramping, what are the chance for this to be implantation because I’m so confused this is my 6 month ttc , my period is never late and is always heavy from day one, and I haven’t even had period cramps like I normally would

Also I accidentally put in the app I had my period even though I haven’t and idk how to fix it
