Hello! Good luck with getting pregnant. While I have not used any ovulation kits with my pregnancies, I knew when I was pregnant by using the rhythmn method that is generally used for NOT getting pregnant. I counted my period days, and the days in between the months, and paid close attention to my body fluids, and temperature so that I knew when I was ovulating. I was usually always a little nautious and just felt crummy on those days. My body fluids were more runny too so I could tell when to really check the calendar. And my temperature usually run around 99 degrees on these days. And on the certain days NOT to have sex, those were the days, my husband and I WOULD have lots of it! I usually took about 3-6 months to really know what my cylce was on. But I can understand if you want to use the ovulation tests to help ease the struggle. I've pulled some information off of the web for you to review if you would like. It's from Wikipedia.com. Good luck, I hope you are able to get what you want!

The rhythm method, also known as the calendar method or the Knaus-Ogino method (named after Hermann Knaus and Kyusaku Ogino), is a method of natural birth control that involves counting days of a woman's menstrual cycle in order to achieve or avoid pregnancy. While the failure rate of the rhythm method is high compared to most other methods of birth control, correct use of the rhythm method prevents a significant number of pregnancies.
A recently developed variant of the rhythm method is known as the Standard Days Method.

[edit] Description and effectiveness
The following describes use and effectiveness of the method for the purpose of avoiding pregnancy.
Most menstrual cycles have several days at the beginning that are infertile (pre-ovulatory infertility), a period of fertility, and then several days just before the next menstruation that are infertile (post-ovulatory infertility). The first day of red bleeding is considered day one of the menstrual cycle. The formula for the rhythm method requires the woman to know the length of her menstrual cycles.
[edit] Knaus-Ogino Method
To find the estimated length of the pre-ovulatory infertile phase, nineteen (19) is subtracted from the length of the woman's shortest cycle. To find the estimated start of the post-ovulatory infertile phase, ten (10) is subtracted from the length of the woman's longest cycle.[1]
A woman whose menstrual cycles ranged in length from 30 to 36 days would be estimated to be infertile for the first 11 days of her cycle (30-19=11), to be fertile on days 12-25, and to resume infertility on day 26 (36-10=26). When used to avoid pregnancy, the rhythm method has a perfect-use failure rate of up to 9% per year.[2]
[edit] Standard Days Method
Developed by Georgetown University's Institute for Reproductive Health, the Standard Days Method has a simpler rule set and is more effective than the rhythm method. A product, called CycleBeads, was developed alongside the method to help the user keep track of estimated high and low fertility points during her menstrual cycle. The Standard Days Method may only be used by women whose cycles are always between 26 and 32 days in length. In this system, days 1-7 of a woman's menstrual cycle are considered infertile. Days 8-19 are considered fertile. Infertility is considered to resume beginning on day 20. When used to avoid pregnancy, the Standard Days Method has a perfect-use failure rate of 5% per year.[3]
[edit] Perimon
A software program developed in Germany from 1995 to 2001, Perimon is a stricter variant of the Knaus-Ogino method. It requires a greater period where unprotected sex is not allowed when used to avoid pregnancy, designating a maximum of 10.5 days each cycle as infertile. No clinical studies have been done to determine effectiveness, but the program's developers claim a perfect-use failure rate of 4% per year. The Perimon software requires a paid subscription.[4]
[edit] Imperfect use
Imperfect use of the rhythm method would consist of not correctly tracking the length of the woman's cycles, thus using the wrong numbers in the formula, or of having unprotected intercourse on an identified fertile day. The discipline required to keep accurate records of menstrual cycles, and to abstain from unprotected intercourse, makes imperfect use fairly common. The actual failure rate of the rhythm method is 25% per year.[2]
