Opk question!

[Lkg]

I was just wondering when using opk's do the lines get darker closer to ovulation, as in build up gradually. I've read that they don't but mine went from really light to quite dark. It's not darker than the control line but not far off I'm going to say and has gradually got darker.
Sorry hope this makes sense!

Mine did too

I second that! Mine get darker as I approach O. Also, mine gradually become lighter after O.

yes, it goes darker when ovulation approaches.

I've used clearblue digital ones too. it gives a blank circle when it didn't detect a surge and a smiley face when it detects a surge. MUCH easier for dummies like me

Thanks for the replies. I've ordered some clear blues but they haven't arrived yet. I'm hoping they get here soon!
