Has anyone cycle change after miscarriage??

Nia
I missed carried at 16 weeks almost 4 weeks ago. I had a D/C to remove the baby. I bled for 4 days and then nothing. Recently it looks like I have ovulated due to the consistency of the CM, and now I'm bleeding like I'm on my period. The only problem is before pregnancy my periods were at the end of the month. This time it seems like it's happening a couple weeks earlier. I started bleeding again the exact day of my D/C.  
Has my body changed cycles due to the D/C?
