Increase Chances of Getting Pregnant
The first step in fertility/family planning is understanding your menstrual cycle.  Every month from your pituitary gland stimulates your ovaries to shed eggs (ovulation). This event happens on 14th day for a typical cycle but it varies based on your cycle duration and various other factors. Released egg moves to fallopian tube and this time is the real high time for the egg to unite to sperm. For you to increase chances to conceive, this egg has to be united to male sperm within 24 hours. The body produces cervical mucus few days before the ovulation starts. These are clear, slippery and white secretions. This fertile mucus is alkaline in nature and protects sperms from acidic nature of vaginal discharge. Most sperms die within 2-3 hours in non -fertile vaginal acidity but in presence of fertile mucus, sperms can survive 2-3 days in reproductive tract.  Hence, it is good to have regular sex leading to ovulation days to increase chances of released eggs being united with sperms during high time. Once egg is fertilized, it travels to uterus within 2-4 days and you are officially pregnant once this egg is attached to uterus lining. In case of non-fertile egg, it will decompose and your wait for next cycle will start.   

    How do I know I am most fertile

     It is a very hard task to pinpoint the point of occurrence. There are several methods used to determine the most fertile moments.  It is not very hard scientific issue but it has to do with many factors. Every individual is different and circumstances are also a factor. Here are main methods used:


Calendar Method

            This method is based on countind days and keep track of your periods. If you consistently have  28 day typical cycle, your ovulation  is likely  to start on 14th day  from start of the period.  You will have to use calendar to mark when your period starts and ends. If cycle is not consistently 28 days, then you will need to subtract 18 days from the shortest cycle to  predict ovulation time from the beginning of next period. So, you will need to add these many days from start of next period to predict start of ovulation..

            The main drawback of this method is accuracy and  error in prediction. Your ovulation and period cycle can vary based on  physical conditions, stress, sickness or any other environmental issues.

Cervical Mucus

           The body produces cervical mucus few days before the ovulation starts. These are clear, slippery and white secretions.  The discharge increases and changes color to egg white just before ovulation starts. The discharge becomes very sticky after ovulation ends and you cannot become pregnant during this time.

           The problem with this method is that you cannot really judge to that accuracy and can make wrong decisions.


Body Basal  Temperature

          During ovulation days or just at the start, the body  temperature goes up by a degree or so.  If you regularly monitor your temperature, you will be able to find the difference in the temperature.  If your temperature has risen and steady, this is the time when you are fertile and ovulation has occurred.  You can use an oral thermometer to keep track of your temperature changes.

         The problem with this method is that  temperature changes  can be due to other factors and it may lead to wrong conclusion. Also, the changes can be very subtle too.


Oval Monitoring  Kit

           Over the Counter Ovulation tests can find surge in LH levels (hormones) before ovulation happens.  LH testing is a reliable way to detect ovulation. Ovulation will occur after 24-48 hours following a positive test.





Pregnancy Test Strip-FDA Approved

One Step HCG Urine Test is a rapid pregnancy test, which you can easily carry out yourself. It detects the presence of human chorionic gonadotropin (“HCG”), which appears in urine very early during pregnancy.



Human chorionic gonadotropin (hCG) is a hormone, produced by the developing placenta shortly after the conception and secreted into the urine. The pregnancy test contains antibodies which specifically react with this hormone.


To use the test strip, simply fill a container with urine and dip the test strip in the container in a vertical position. Your results appear within five minutes. This test is capable of detecting human chorionic gonadotropin or hCG (a hormone present in women's urine during pregnancy) at levels of just 15 mIU/ml/hCG. That means you can begin testing accurately as early as six to eight days after conception - well before your first missed period!

If you are fertility charting, and you know your ovulation date, you may begin testing as early as 7-10 DPO (days past ovulation) when the hCG level in urine will, on average, reach 15 mIU/ml. We recommend using a first-morning urine sample as this will contain the highest concentration of hCG.

Ovulation Test Strip-FDA Approved

One Step Ovulation Urine Test is a qualitative test used to predict when there is a LH surge, and in turn, when you are likely to ovulate. Experts state that LH testing is a reliable way to detect ovulation. Ovulation will occur after 24-48 hours following a positive test.



The length of the menstrual cycle is the duration from your first menstrual bleeding day to the day before the next bleeding begins. Determine the length of menstrual cycle before test. Please refer to the chart below to determine when you should start testing. If your cycle is shorter than 21 days or longer than 38 days, consult a physician. If you do not know your cycle length, you may begin the test 11 days after your first period since the average cycle length is 28 days. Perform 1 test each day over a 5 days period, or until the LH surge has been detected.


If you're trying to conceive, One StepTest offers low-cost, high sensitivity ovulation predictor strips.  Test strips are placed vertically in a container of urine. Both tests provide accurate results in just minutes, allowing you to predict peak fertility.

Ovulation predictor tests work by allowing you to detect your monthly LH Surge - the sudden and dramatic increase in luteinizing hormone present in your urine just before you ovulate. Lh is the hormone that facilitates ovulation (the release of the egg). When you detect your LH surge with an ovulation test, you know you are fertile!

Since the best time for fertilization of the egg to occur is within 6 to 24 hours after you ovulate, correctly gauging your body's cycle is extremely helpful in increasing your chances of becoming pregnant. Our ovulation tests detect LH with a sensitivity of 10mIU/ml/lh - and all of our tests are brand new, with an expiry date of 2 years!
