My period was three days according to my cycle and then I got my period . It started as normal but then got a lot of blood clots two days into period and now on my sixth day when my period usually only last 5 days at the most, I am now experiencing brown spotting when I wipe. Can you explain what and why this is happening? Any chance I could be pregnant with the symptoms listed? I have not taking any hpt tests. Also if I was pregnant, would a pregnancy survive with the said mentioned symptoms?
