Regarding pregnancy. I still pregnant?

Im a 20 year old girl with pcod problem. I had unprotected sex on march 1st week.  My last periods was on February 1st week. I checked pregnancy twice with preg kit at home.  It was negative. So i have taken regestrone tablets for 3 days twice a day.  After  4 days stopping the tablets i got very light periods just for 2 days on april mid... I don't know whether its spotting or periods.  And for may month i didn't get my periods. So i consulted a doctor in practo.  My main question is am i pregnant???   she said u r likely not.. She told me to check again in home and prescribed me meprate 10 mg twice a day for 5 days.. This is the 9th day after stopping tablets.. And i checked pregnancy test with kit.. It is negative. So what shall i do now?? Am i still pregnant?
