2 periods in 1 month, only 2 days apart

Tyria
Hi my names Tyria I'm 25, I've been ttc now for about 2 months. I recently lost my baby in July because of an early labor, I was only 20 weeks 5 months pregnant at the time and because of how early I was my son didn't make it. My question is my cycle ended Tuesday the 15th, my partner and I was intimate Thursday and everything was fine. Friday night I noticed lite pink blood. On Saturday it was a lite red color. Sunday it was a brownish red color. Now it's Monday and I'm still bleeding/spotting and it's more like a lite red color. Has anyone ever experienced this before? I also have been having lite cramping since saturday.
