I chart using fertility friend, and I use opk's to figure out when I 'O' because I can't temp every morning - I forget, wake up at different times, whatever.
Anyway, OPK's confuse me for a couple reasons. This morning, I got a line, but a faint one. Sometimes I get a really obvious line, which fades to a lighter line a few days later (I am a curious person and so I usually take 3-5 OPK's a month).
So, from the time there is a really light line, am I about to O, and then when the line is the darkest, is that the most likely day, and then the hormones fade, so I get lighter lines? How do you know, if you test 3-4 days in a row and get lines each day (except the first in this case)?
By the way, we DTD 2x last night, so if this morning's line is right, we should have hit it just perfectly, right?
