Hi, I feel sorry about your Ist loss. Before taking any treatment please confirm your pregnancy
status. Go for an ultrasound
pelvis to check for fetal heart beat after that you may ask your doctor about any treatment. Remember every case is different & having one miscarriage
do not mean that this will happen again & again. 1 in 4 to 1 in 5 normal women may have one miscarriage. Meanwhile relax yourself, do not do any exertion & avoid penetrative sex. Best of luck.
