Smile ovulation test versus two line ovulation test?

Question

Hi ladies!
Need some opinions out here!
I’ve been using the two line ovulation test and can always track my ovulation this way we’ll. 
But I know a lot of people use the clear blue smile face ovulation tracker. 
What’s the difference between the two? Should I maybe try the smile one for better chances ttc?

Answer

The only digital test that offers anything more than line OPKs is clear blue advanced digital OPK. It tests estrogen in addition to LH. So it can give you more fertile days. 
I used it for 3 cycles in addition to line OPKs and prefer the cheapies. I quit buying the digital. Why?
1. They’re expensive. It may be great if you’re one of the lucky ladies that get pregnant within 3 months but that adds up if you end up like me...on my 10th cycle. 
2. I had unreliable results. One cycle it would flash for ZERO days before peak and the next it would flash for 5 days before peak. 
3. They’re harder to comply with instructions. You have to use first morning urine to get accurate estrogen readings to get your blinky smile. I can’t walk in a straight line first thing in AM. I really hate morning testing. I often wake up a couple hrs before my alarm and if I have to pee I have to test to get accurate results (otherwise it will screw up the algorithm and give you false results).  And then I can’t go back to sleep. 
4. If you continue to use first morning urine after you get blinky (high) reading you can miss 12 hrs of your solid smile (peak). Especially since LH tends to rise later morning or afternoon. I’ve also had peaks in AM when I was negative the night before so I can’t just change to testing at night (once you get blinky you no longer have to use FMU). That leaves me testing twice a day. Which takes me back to problem # 1.
5. Out of a box of 20 I usually have 1-3 that doesn’t  work and gives me an error.

Answer

I prefer the digital tests because you either get a smiley face or you don’t. No second guessing if the lines match, no confusion
