There is minimal risk of miscarriage about 1: 1000. We do not know why it happens or to whom it will happen. It does not cause any birth defects or any harm to the mother. The risk of infection is also very low, 1 in 1000.
You are made to rest for half an hour after the procedure. The fetal heart beat is checked and then you are sent home. Most women have no problems, but you might have a bruise, spotting or cramping.
