Hemorraghic Cyst and late tablets. Days?

I had hemorraghic cyst 22*20mm. My dr closed follicular study on day 13 due to cyst asked me to visit next month for Follicular  study and prescribed me duphaston 10mg twice a day. i went out of station and couldnt get tablet on day 13 i started tablet on day 16 only. now on day 22 i had light spotting went to dr to check. she prescribed me without mentioning days told me to take susten 300mg once a day (addition to duphaston 10mg twice a day) till duphaston gets over (5days of susten). i forgot to mention her abt the duphaston i took late by 3days. now my doubt is i have duphaston for 8days. should i add susten 300mg 8days or stop it by 5 days? already previous cycles they had prescribed me both tablets for 16days. now i dont know what to do.
