Meet Joann

I used the KNOWHEN® kit for about two months. I did a trial and we correlated the results with a sonogram and bloodwork. It worked for me and it was easy and afforable. I do many things throughout the day so just swabbing for a few seconds is convenient for me versus going to a GYN or going on birth control pills.

Meet Laura

The KNOWHEN® kit is a wonderful product in order to control what I want to do with my life. I am eventually looking to have a baby although right now I am not looking to become pregnant. Using the product now helps me find out how my body works and understand whether I will have problems when eventually I want to be pregnant.

When I saw the ferns, I was shocked that I actually saw what the manual told me I would see... It was there and I was so shocked and happy to know that I was ovulating right after ending my contraception. This product actually works and it was just the best.

I like to use the KNOWHEN® kit because it is time-efficient and money efficient. It has a lifetime guarantee so you don't have to worry about constantly buying the product over and over again.. You also don't have to worry about the product taking up much of your life because you wake up, in five minutes, you can put the saliva on the product and wait to see if you are ovulating or not.
