On day 47 of my cycle, 4 months after miscarriage?

See the doctor. I had to have a D&C 2 weeks after my daughter was born. I got my period 30 days later and then not again for 54 days. I called the doctor and we talked and he checked me out. he said sometimes after birth ( or miscarriage) and a D&C is involved, it takes your body several (3-5 months) for things to go back to the way it was before the pregnancy. I hope this helps! Good luck!
