Two years ago I had a natural miscarriage, then got pg again right after the m/c and had a perfect normal pregnancy, and the baby is 9 month old now. After the baby, my periods have been more or less regular. No unusual cramping or pain or anything of the sort.
I had a normal period a week ago and thought it was over. Then, three days after it ended, I started another period, pretty much like the one before it, regular "old blood" like bleeding, no cramps or pain.
I know that it takes a while for periods to get normal after having a baby. But she is 9 months now. Shouldn't my periods be regular by now?
I am NOT on a pill or any other form of contraceptive and I am not pregnant.

Please help!
Thanks.
