Spotting & tissues stopped. 2 week?

It's  stopped spotting,small tissues,abdomen pain. does it mean tablets are working?  i will continue my pregnancy?will it be successful after 2 weeks & heartbeat can work after 2 week? please advise.           Previous question: Iam 6 week pregnant i had PCOS so doctor suggested me to take Yasmin tablet for 3 month so i took from October to jan and i got positive pregnancy test in Feb... As per LMP iam 8 week pregnant but as per scan report iam only 5-6 week pregnant as per doctor this issue because of irregular in period cycle... So now i had ultrasound heartbeat was not heard because still iam 5-6 week pregnant... And all of sudden iam passing small apple seed size tissue along with urine and very small line  spotting from 3 days back pain,abdomen pain from 1 day. because of this issue Doctor suggested me to have tablets(Dydrogystorene & Progesterone) to follow for 2 weeks and have another ultrasound after 2weeks.  successful pregnancy or i will have to hear bad news please advise.
