I was five weeks pregnant. I had miscarried as doctor said it was chemical pregnancy. In 6th week I got my normal period and it lasted only for four days like my usual period, but doctor said I will get one week to ten days of period after miscarriage. Is it normal to get only four days of period after miscarriage?

So sorry to hear about your miscarriage. The bleeding you experienced could be normal for you. The time frame will vary a bit from person to person. The bigger concern would be if the bleeding was prolonged.
