How to Tell When you are Ovulating with a Fertility Microscope

How to Tell When you are Ovulating with a Fertility Microscope

Fertile Focus Fertility MonitorFertility microscopes are one of the easiest tools you can use to pinpoint your most fertile times of the month. Compared to stick testing and charting, using a fertility microscope is also a more fun way to witness your hormonal transition towards ovulation.

The size of a lipstick container, this fertility tool has 97% accuracy in alerting you to ovulation up to 72 hours in advance. This allows you enough time to get you and your partner’s schedules coordinated 🙂 .

The Fertile-Focus fertility microscope allows you to identify you most fertile days by testing and viewing the visual changes that take place in saliva throughout your monthly cycle.

How it Works

Just prior to ovulation, women experience an “estrogen surge,” and a distinct fern-like pattern becomes visible in saliva due to the hormonal changes. Fertile-Focus provides the highest quality, powerful 50x magnification lens for easily identifying these crystal “ferning” patterns.

To use Fertile Focus, simply place a drop of saliva from under your tongue on the lens. Once the sample has dried (typically within 5 minutes), press the LED light button and view resultant pattern through the lab-quality magnifying lens. If you are ovulating – or if you’re about to ovulate – a distinct “ferning” crystal-like pattern can be viewed. This is your indication that it’s time to make love for baby-making purposes!

  2. Avatar ttcing and using fertile focus to track the ovulatiion i’ve started using it last month and it was very useful but this month I dont know what is the problem i’ve ovulated the past 6 days but even today i’m still seeing strong ferning pattern,my boobs are bit heavy and sore from the second day after ovulation. Pls help. Thnk you

    • Hi Mulalo,

      Below is an explanation from the makers of fertile focus and this should really help you understand:

      How does Fertile-Focus work?
      Fertile-Focus detects hormone changes that occur prior to and during ovulation. As estrogen increases, “ferning” or crystal patterns can be viewed in dried samples of saliva (due to elevated quantities of electrolytes that will appear in your saliva). These ferning patterns indicate that ovulation is about to take place. The duration of a woman’s fertile period is typically around six days, ending 24 hours after ovulation takes place. Unlike urine LH tests, Fertile-Focus allows you to track fertility and your cycle changes throughout your entire menstrual cycle. When you observe a positive result (crystal/ferning patterns), ovulation is likely to occur within 24 to 72 hours.

      •Follicular Phase: Early part of your cycle (Negative Result): Low Estrogen Levels. You’ll See Dots, bubbles, and lines. You are not likely fertile.
      • 0-2 Days (Transitional): Increasing Estrogen. You’ll see incipient ferning patterns, light ferning at margins of result. You are approaching your most fertile time.
      • 2-4 Days (Positive): Estrogen Surge: You’ll see strong ferning patterns: You are at peak fertility.
      • 0-2 Days (Transitional): Decreasing Estrogen. You’ll see diminishing ferning patterns, light ferning at margins of result.
      • Remaining luteal phase following Ovulation (Negative Result): Low Estrogen Levels. You’ll See Dots, bubbles, and lines.

      Are ferning patterns observable at other times in my cycle?
      A second second estrogen surge may occur right at the end of your cycle. By monitoring cycle length, and keeping daily results, the second surge should not be confounded with the estrogen surge preceding ovulation. Also, as different women produce differing levels of estrogen, ferning patterns may vary a bit in appearance and duration.

      I hope this helps you.

      Best Wishes,


  3. I’ve used a couple of these microscopes in the past and they are incredibly difficult to use if the instructions are poor. Your site provides great screenshots of exactly what to look for which I think many people will find very useful.

    What a breakthrough for women who are trying to get pregnant. It is amazing that you can track ovulation through a drop of saliva. Fertile Focus sounds like the perfect tool for women to keep on top of their cycles. It is difficult for women who are having trouble conceiving not to get stressed while trying to better their chances of getting pregnant. This fertility microscope will give them a little piece of mind while going through the process.

  5. In the past, to predict my fertile days I’ve been taking my BBT and using OPK (ovulation prediction kit). But sometimes I have problems reading the results on my OPK’s. Plus I’ve had people tell me not to rely on the result anyway. Is this true? Which method do you prefer for pinpointing your fertile days and your ovulation day? Which one is more reliable and less likely to be misread?

    • OPK’s can be frustrating to work with as a very faint line counts just as much as a strong line (unlike pregnancy tests). They also must be taken a couple of times around when you think your most fertile times are. I think the best way is to use BBT fertility charting with the ovulation microscope. Fertility charting, if done at the same time every day, is the most accurate way I have found to track ovulation. The only issue is that it tells you after you have ovulated, but if you chart consistently you will begin to see a pattern emerge. The ovulation microscope is nice to use in conjunction as you can begin to see the crystals changing as ovulation nears. Hope that helps!
