Hi, I Am 6 Weeks 5 Days Pregnant, I Do

Hi, i am 6 weeks 5 days pregnant, i do not have any symptoms, except a little bit of cramping in legs and a bit in stomach but that does not last more than i minute, i am working but don't have stress in office, but in personal life have a bit of stress, i am cooking for myself and driving too. Yesterday i had a slight stomach cramp that as usual lasted only a minute but soon after i had a little bit of bleeding which eventually stopped but throughout the night i had little bit of dark brownish bleeding that was not very much, i went to thw doctor. They checked the baby and heartbeat and said all is well. They gave me a shot and i am taking duphaston for past one week. I hope all is well and it is not signs of miscarriage. Please advise
