So discharge .. spotting ... flow - sorry this is going to be icky!
I think I need clarification!

What do you term spotting?
Colour/consistancy/quantity (sorry ... did warm you it would be icky)
When does spotting become 'flow'
I have had 'spotting' for about 4 days now .. except on Sunday it got heavier and was very like my usual 'flow' ... but now its almost gone again

...
I though Sunday was CD1 ... it seems my body disagrees!
I usually spot for 24-48 hours before AF (browny pink then goes red and 'flow' takes over) .... but this is heavier (when it appears its a sticky thick creamy consistancy .. sorry TMI

)
Ok .. now for the nasty icky bit ... colour ... It's brown, got lighter today but definitely brown not pink or red ...

I'm really confused by this - am I normal?
