First time TTC - First time using OPK!

So, my hubby and I have been TTC for 10 months now, and each month, I get my lovely monthly visitor. This is my first time TTC, as I have never had any children before. I am 25 and my hubby is 46. He has had 2 kids with his first wife.

When telling a coworker of mine about how I have had zero luck TTC over the last 10 months, she was like,

Coworker: “OMG! DO YOU USE THE OVULATION PREDICTOR...with the SMILEY FACE?!?”

Me: “No? I just use this app...”

and she then went on to tell me that she has recommended it to 2 of her friends when they were not successful in TTC, and then BAM! Just like that, her friends told her they were pregnant! Either that exact cycle or the next cycle after using the Clear Blue OPK!

I just wanted to know if anyone had success stories of getting pregnant after using this OV prediction stick?
