Post-Ovulation Spotting?...how dark is too dark?

Mandy
Hey ladies! Hubs and I have been ttc for ~4months, and I have had little twinges and mild cramping from 6-11 DPO. Today (day 11 DPO), I've had a small amount of dark brown spotting. In your experience, how dark has "in-between" bleeding been when it wasn't AF? I'm trying to be positive, but realistic... Thank you in advance!!
