So I'm 10 dpo and last night had a bit of blood when I wiped and some brown CM. I never bleed between periods so I was hopeful that it might be implatation but I've done 2 internet cheapie tests today and both BFN. AF due on Tuesday but I'm driving myself crazy. I've had no more bleeding since last night - if it was AF I would normally have full flow after spotting the evening before. I've had no other symptoms so what is going on?!?! If it was implatation bleeding, should I have had a BFP today or might it take a little more time for it to show up on a test?
