My period was due last saturday/sunday but never arrived. On the tuesday following a few crampish pains in my tummy very small bleed which were normalish in colour (as far as I remember) and then the next day a tiny spot of brownish blood. As by the saturday I had bleed no more I decided to do a pregnancy test which was positive. I assumed then that the small bleed was a implantation bleed but have read more on the internet and it seems that this happens much sooner after conception and not normally after when your period was due. I am now worried that this bleeding is a sign that something is wrong. I am feeling all the usual pregnancy signs sore boods/tiredness etc. Has anyone else experienced implantation bleed later that the norm?
