Hi Alison, thanks for your reply. My last period started on 25th July, I had unprotected sex on august 6th and dark brown spotting for no more than an hour on August 15th. My period was due on august 22nd. This morning there has been some light red spotting on the tissue when I wipe but apart from that, nothing. The last pregnancy test I took was on August 19th. I have been feeling tremendously tired and sleeping most of my spare time away. I can't imagine what's wrong with me?
