Hi , I am hypothyroidic for almost 9 months. On medications for it as well. I am experiencing lighter periods since almost like last 4-5 months or may be from last 6 months not actually been observant about it. My cycles are regular but I have very light flow and the flow is only for 2 days . Sometimes I even have calves pain during periods including very light cramps. I am kinda worried about the light or only 2 days flow. Is there any tests i must take to see if there is any issue? Awaiting response. Thank you.
