I'm experiencing irregular period problems. My period was due on December 30th, but I noticed spotting on December 26th. After 2-3 days, around December 28/29, my period started, but the flow was very light and infrequent. Initially, the blood was brownish, but now it's normal. However, my period has continued for 12 days without stopping. I faced a similar issue in October, and my doctor prescribed Pause 500 and Zydus tablets, which helped for two months. But the problem has recurred. I was diagnosed with a cyst 2-3 years ago, but my doctor said it was small and not a concern. Could you please suggest some medication?
