IC OPK VS DIGI - bold lines but no smiley!

[My_Story]

Title says it all ladies! Anyone able to shed some light?!
CD18. Irregular periods so don't know how long until AF is due.
How can I have bold lines like this and get an Unfertile face?!

Thanks

This is happening to me! I posted a new thread then found yours. I just started femara this month. I did actually get a blinking smiley this morning but the cheapie is now BLARING positive and the actual lines on my digi are not as dark.
