Hello doctor! I have menstrual disorders, for 2 months now I still haven't seen it. After going to a private clinic, they gave me medicine to drink to induce menstruation including: 1 pack of round white pills, 1 pack of daily birth control pills. The doctor instructed me to take the round white pills for 10 days, then stop taking the medicine and my period will come for 2-7 days. When my period comes on the 2nd day, I will take the daily birth control pills. But when I took the round white pills, I felt dizzy even though I had eaten. I took the 2nd pill and my period came, so I stopped taking the medicine. I went to the clinic where I was prescribed the medicine and asked, the doctor said the medicine would cause dizziness after taking it and told me to take the daily birth control pills as prescribed, and when I finished the medicine, come back for a check-up and continue treatment. I am very worried, maybe it is because I am stressed or have changed my lifestyle causing menstrual disorders. Will the medicine the doctor gave me have any effect? And will taking birth control pills regularly like that cause infertility? I hope the doctor can advise me, thank you doctor.
