I need a little help from those who use OPKs, I've never really used them before. I'm pretty sure I O'd on Sunday based on CM/CP, but I can't be sure since I'm not temping. I just got my ICs today in the mail. I peed on an OPK just to see and I got a line that is just barely negative.
My question is, is it normal to get a test that looks so close to positive AFTER you've already O'd? In your experiences, after your surge does the test line go away pretty quickly, or do your tests continue to be close to positive for a few days after?
