Hi i am having my period since feb 6 but since yesterday i started to feel lower tummy cramps until i thought of buying pregnancy kit, the result was positive so i decided to consult a doctor, since i am bleeding the doctor gave me duphaston and advice to take it thrice a day, the bleeding eventually stops, what could that mean, am i really pregnant? The trans abdominal ultrasound showed no sign of me being pregnant but dr says it might to early to assume......
