CD 15 - from this day onwards I had light cramping and bloating.
CD 23 -I had a blood taste in my mouth. Cramps were heavier now and felt exactly like AF.
CD 24 - I had what was implantation bleed
CD 24 - I then tested with a First Response test and got a line so faint I thought I was imagining things. It got progressively darker after that.

At the time my cycles were an average of about 26days.

I have my fingers crossed for you!
