Lol.... Don't know why a 1992 date posted, made me giggle though.

I got my first blinking smiley this afternoon too! After days using the sticks and coming up with a blank circle (my fiancé and I call those one "failure sticks", the cats like to sneak them out of the trash can and play with them....) I was so excited to see that blinking smiley because I expected it sooner. Now10/17/1992, we just keep testing, cross our fingers and pray for potent baby dust. Good luck to you!

The headaches can definitely be attributed to hormones. I use the cb also and haven't gotten my smiley yet. Hoping it'll come in the next couple days!! Good luck. 

Thank you! I guess I am hoping for a solid tomorrow or Tuesday. I have had a horrible migraine all morning. Could this be hormones? 

I use this OPK I'm getting circles but I'm hoping to get a flashing smiley Monday or Tuesday with a solid on Thursday 

If you are using the cb OPK that shows high and peak fertility, the blinking smiley shows high (oestrogen surge) and a solid smiley shows peak (LH surge ie just before O). ​​So if you have a blinking smiley you still need to test until the solid smiley.
