I don't temp but I have 10 OPKs ready and waiting for action in the bathroom! I would say that the real full flow new blood didn't start till about CD3 *toddles off to check journal*
Usually I have a good idea about when my cycles start and end, but the week long spotting and brown discharge really threw me this month.
*edited to add that although i had brown discharge and needed a pad actual 'flow' didn't really start till about CD5*
Off to change CD1 then ..... will move it forward 3 days I think ...... I said the 18th was CD1 .. but full flow didn't start till the 22nd
Will make CD1 the 21st ... it was the fisrt day of 'proper light flow' ... my poor journal!!!! It going to be so messed up this month!!
