I was having period pain for which I consulted a doctor, he did USG along with few other tests but found nothing. He then suggested few iron tablets following which my pain subsided but after I finished the course, I started having heavy bleeding during periods, he then suggested harmony F for 3 cycles but once I completed the course, I skipped a cycle and he suggested Deviry 10. I had the medicine and since then I am getting my periods but my flow is scanty. Almost 2 days instead of my normal 5 days. What can be the cause? Is it because of the medicines?
