Ok just wondering if anyone knew the answer to this.
I have used an opk for the last 4 days, the first 3 days there was clearly no 2nd line therfore meaning i am not ovulating.
today i got a 2nd faint line, not as strong as the first ine so although i know this means i have still not ovulated do you know if this means it could be on its way?

i am already on CD 18, FF detected i O on day 14 until i entered todays temp and it has now changed to O not detected.
Thanks
