Period after a miscarriage!

So I had a miscarriage in December 3rd and I bled for 6 days and then bled again a week later for 5 days. So I went to the doctor and he said its my body's hormones trying to get back normal.. But I started bleeding this afternoon Wichita I thought it was my period cause glow says I was gonna start on the 16th but it was late now when I started bleeding it was very light. I don't know what is going on it has now stopped. My periods are usually normal but since I lost the baby it seems like im all out of wack were gonna try again as soon as I start ovulating but I don't know when since AF wants to be stupid. I just need someone to talk to who has experienced the same thing. Please help me have a peace of mind....
