11 days of spotting? Help!

Okay so I'm not on birth control and I had sex and the condom broke but he pulled out right away. That happened on June 17th. Just the day before on the 16th my period ended and <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> said I wasn't fertile. On the 27th I started to get very minor spotting which gradually increased so that I had to wear a menstrual cup instead of liners.  Now it's the 7th of July and I'm still bleeding, but it's lighter than a normal period. 
Does anyone know what could be going on? Implantation bleeding doesn't last that long right? Is it a sign of a miscarriage?
I'm getting worried since I've never had spotting last so long, I feel like I'm going to just keep bleeding forever. 😭
I scheduled a gyno appointment, but it isn't for another week. Please leave a comment if you have any idea what could be happening!
