Hello, My sister is of 6 weeks pregnant, she had her first ultrasound scan on 24th of December and dctr said the baby is in correct position and also the baby's heartbeat is good. But when she removed the tube that she used for the scan, my sister and the dctr saw little bleeding(brown in color). The dctr said its normal and not to worry.. She had lite brown spotting for two days and then it turned white and normal and again today she is seeing Red spotting.. When she called the dctr, she suggested her to take bedrest and to take injection named "Progesterone injection IP named Gestone" Is this spotting common or does it lead to any miscarriage? Plz suggest!!
