My period was due last week. About a week or so before it was due I had brown sticky discharge for a few days and then it went. It has now come back a week later.
From looking on the web I believe the first time it could have possibly been the end of my last period- lining fully emptying (or something I can't remember what was said) and now it is the start of my period.

Am I right? Should I be concerned? What is going on?

Thanks
