With DS1 mine was 8 dpo, and it was brown and not much - probably the size of a twenty cent piece. I noticed it on my knickers, but there was never any onthe toilet paper when i wiped. This was when i knew straight away that FET had worked.

With DS2, it was a natural cycle, and was 11 dpo, and i was waiting For AF as we were starting a stim cycle. There was a few bright red drops when i wiped and i thought it was AF. Same again the next day, bright red drops. Three days later i tested and was positive.

So to me, implantation bleed can be a variety of different Colours, doesnt have to be one colour, and can occur on a number of different days. Theres nothing to do but wait!!! J. Xoxo.
