Hello. I am 34 years old, had a miscarriage one month ago at 9 weeks of pregnancy, on 31 may, after which I had a vacuum aspiration . Two days later had an ultrasound which showed some blood left and was given a cytotec pill. The bleeding lasted for almost 5 days after the miscarriage. The period came exactly 29 days after the miscarriage. Should I be worried about the blood left in the uterus and have another u/s? What if it is not clean again, do I need d and c?
