What is the best app to use that can read these test for me? I have premom app and Femometer app and they give me two different results.

I use the Glow app. It can scan the tests and evaluate for you. You can also manually enter information based off a color guide they provide.

I’ve been taking for 2 weeks now to start tracking my cycle. each day has tested positive, with a really dark test line. possible?

Both test line and control line have to be dark for it to be positive. If only one line is dark and the other line is lighter at all it’s negative!

I've been getting results in "positive" 3 days straight. Has it happened to anyone else?

In the beginning of your surge, the lines start equal. As your surge progresses, the test line gets darker and darker. It will be at it's darkest immediately before your egg is released. Right after your egg is released, it will go light again, then fluctuate a little for the next day as the hormone comes back down. However, you will never get another stark positive like the one right before ovulation began. When the egg is released, your surge ends and ovulation begins. The egg then sits there for up to 24 hours waiting to be fertilized. This is why it's best to "baby dance" at the END of your surge or even after it has stopped and ovulation has begun. The surge can be anywhere from 12 to 36 hours long depending on when you catch it. I recommend testing every 12 hours when you're getting closer to your surge days. After the surge, ovulation lasts 24 hours. Hope this helps.
