My periods are regular and are the last week of every month. My last period ended on the 4th march and yesterday i had a brown discharge which got thicker over night and now i am bleeding like im on my period again. I have done a pregnancy test and it is negative, i have only slept with my partner and vice versa, i had a std check (the full works) and they all come back negative too. I gave birth to a still born baby at 20weeks pregnant in september just gone and im starting to worry that something may have caused a problem so that i wont be able to have any more children. Am i broken?
