Periods, HELP

Katelyn • 🌙✨
So I had my regular period 5/11-5/17 like normal, 5 days later on 5/23 I started bleeding again until 5/29.. I called my dr they just said it's probably access period blood that got stuck or something not to worry.. Well yesterday I started spitting again like it did in the second "period" before it got a little heavier. What in the world could be going on?? 
I'm callin my dr again tomorrow to talk to them but I'll prob get the same response. I don't feel like this is normal.
