Is a dry opk accurate?
Are results still accurate once an opk is dry? I took one the other day that looked almost positive when I checked it, and when I looked at it the next day it looked positive. I know pregnancy tests aren’t accurate after the specified window, just wondering if it’s the same for opks. After that one my tests started to fade and now they seem to be getting a little darker again, but no clear positives unless that one counts as a positive. I have no idea what’s going on this cycle - it’s the first one after a chemical pregnancy.
