AF was due to arrive 3 days ago and still nothing!! Last night I went to the toilet and when I wiped I noticed i had a bit of white discharge with 1 small streak of blood in it. I've woke up this morning and checked again and nothing, just back to white discharge again! Is this implantation bleeding? I never noticed any when I had my daughter so it's all new to me! Could this be why my pregnancy tests have been negative? The last time we DTD was 11 days ago.
