How it works: If you’re not into the idea of the mess of peeing on things, and you’re interesting in creating your own little science experiment, this saliva test might be right for you. Just place a drop of your saliva on the lens and let it dry. Then, take a look through the microscope. If you see a “ferning, crystal-like” pattern, that means you’re ovulating or about to ovulate (within three to five days).
How accurate it is: It’s said to be over 98 percent accurate.
Pro: You can take it anytime, anywhere, and reuse it every month.
Con: Some find it tough to read. Knowing whether or not there’s a fern pattern isn’t always so cut and dry.
Bumpies say: “I did see ferning this month on the Fertile-Focus, and that did coincide with my positive ovulation predictor test and temping. So, it seemed to give the proper readings. But I don't think I'm going to abandon my other tools just yet and only use that. It's kind of neat though, and I like the fact that it's reusable.”
“I really like it because I can start to see partial ferning, building to full ferning earlier than I would get a positive ovulation predictor test, so that gives me a heads up to start getting ready for ovulation. You do need to get used to what your cycles are like with it, just like you would with any other tool.”
