menstrual circle

It is important to call your doctor, as it does not sound like you understand what you should be expecting from your prescription. I would call your doctor or speak with a nurse for clarification on your treatment, by asking the following questions:
1. Is the medication considered successful if I experience a period? Does it matter if the period is exceptionally heavy or longer duration than usual?
2. What warning signs do I need to watch for?
3. After I stopped this medication, I did experience a period, but it was much heavier and longer in duration than my previous periods. Is this harmful? What should I expect for my upcoming periods?
4. I am continuing to experience spotting (what you describe as little drops of brownish color blood). How long should I expect to spot or have "breakthrough bleeding"? (this is just a term used when you bleed in-between periods).

Please let us know what information your doctor provides, and we can help clarify any information or further treatment options you need help with.
