Aussie, it doesn't look too bad - I have included a link to my charts for you - not sure what will come up ie whether it will just be my last chart or if the two of them will be in there. As you can see my charts were all over the shop at times but the super chart analysers kept informing me it looked good for the month I did fall pg.

tk1999's chart

I think yours could be an implantation bleed but it is hard to say at this stage - I agree with Saram it will be interesting to see what tomorrow brings - the white circle on CD17 - was that a late temp taken? What is the reason it was discarded?
