Weird how we're all different isn't it? I can only go by my last pregnancy where my line was dark 4 days after period due (on a 35 day cycle) but nowhere near as dark as this one.
It just feels really weird as I didn't even know I was ovulating, I HATE not knowing things!
I have had a sneaky try with my doppler and nothing yet so likely I'm only 6 or 7 weeks I guess, maybe 8. Aghhhh I want to know now!
