Has anyone else had this problem?!

Gwen • Had my sweet rainbow baby girl on April 3, 2017! 👶🏻🚼🍼 So incredibly blessed. ❤️
My period started 4 days ago and it's been NOTHING but old blood and VERY light. My last period was like this as well but longer than normal. I don't even know if I should consider these periods since they're old blood. Ugh
