With unpredictable cycles, ovulation tests can fall short

Inito gives you the right days to try so that you're not left guessing.

How does Inito work if you have irregular cycles?

1/3

Time intercourse accurately

Ovulation might be early, late, or not happen with erratic cycle lengths, making it easy to miss your fertile window. Inito tracks LH, estrogen, and FSH to pinpoint the right fertile days, no matter what your hormones do.

I discovered my estrogen stays really high the entire month but Inito still adjusted after learning how the hormones in my body work! I noticed that I consistently ovulated later than I had thought.

2/3

Bleeding isn't proof of ovulation.

With irregular cycles, ovulation may or may not happen. And just getting your period every cycle is not a sure sign that ovulation is actually happening. Inito measures PdG to confirm ovulation, so you know whether your body is truly fertile and can plan with confidence.

“I have struggled with infrequent cycles. Without Inito, I wouldn’t know how badly I needed intervention. My doctor advised me to add letrozole. I was able to easily see when ovulation happened.”

“With OPKs, I would double peak. Inito took such a weight off my shoulders by being able to tell my first peak wasn’t successful ovulation. I had given up on it happening naturally, Inito helped me feel more in control.”

1: "Most precise" refers to system-level precision measured in controlled laboratory testing, based on lower between-device variability across key hormones, concentrations, operators, days, and
strip lots. Compares Inito to other U.S. over-the-counter at-home fertility monitors that provide numeric or graded hormone values and measure the same hormones as Inito.
