Possible implantation?

Diane • DD aged 9.5, DS aged 8, and DD aged 1.5 DH aged 33 expecting a baby boy January 2017
So... I'm obsessed. Thinking about it 24/7. I'm on CD24, 8/9DPO I think. Did my normal CM check this morning and to my shock it was brown with a tiny spot of blood. This has my mind reeling about possible implantation! I have had cramping and slightly achy boobs, bit of nausea but think I had a bug. 
​Think I will try and wait till this weekend to test ... Easier said than done!! 
​Good luck ladies!!
