I am diagnosed with PCOd 4 months earlier. I used to have periods delayed by one week to 10 days. hormonal and thyroid test results were normal. my last period was ten days earlier( due by Feb 8 th. But came on jan 28). Has started with brown dis.It had stayed for 8 days. 3 days of brown bleeding and 5 days of red blood. I had un protected sex 4 days back and today there was light brown spotting. Could this be starting of my period earl again as last month since my next period is due by Mar 8?
