BFP Ovulation Test Strips accurately identify your LH surge to predict ovulation, made in N. America.

Pinpointing your ovulation date, the day in your cycle when the egg is released, is critical when trying to conceive. Why? Because fertilization can only occur within 6 to 24 hours after you ovulate. For this reason, correctly identifying your ovulation date should be at the top of your trying-to-conceive “to do” list. A tried-and-true method for predicting ovulation is the ovulation test strip—a urine-based test that detects the “LH Surge,” the sudden, brief increase in luteinizing hormone present in your urine just before you ovulate.

BFP Ovulation Test Directions: Dip the tip of the strip into a container of collected urine for at least 5 seconds. Then lay it on a flat surface and wait for five minutes. After five minutes, your test will be ready to interpret. Complete ovulation test strip instructions (including how to interpret test results) ship with every order.

BFP Ovulation Tests are made in N. America. Individually wrapped in foil packages. BFP Ovulation Tests are “just manufactured” with an expiration date roughly 1 year from your purchase date.

FAQ

Here’s our list of most frequently asked questions. If your question is not listed or you need further clarification, please contact us directly.

How many mIU/L?

The BFP ovulation tests are testing at the 25 miu level.

When should I start testing?

This is different for everyone, and is dependent on your cycle length. Please use graphic above (and included in the instructions) to determine the cycle day you should begin to test.

What time of day should I test?

You will want to test between the hours of 10am and 8pm.

How do I know the test is working?

You can confirm that the test is working accurately if you receive a valid control line. A test without a control line would be an invalid test, and should be discarded.

Is there an expiration date for these tests?

The expiration on our tests are approximately eighteen months.

How is this test different from the test strip format?

The only differences between these tests is how you use them. For the test strip format, you will collect a urine sample and then dip the test into that collected sample. For the midstream format, you will hold the test midstream while urinating. Otherwise, the tests have the same accuracy and sensitivity.

Will FMU cause a false positive?

We do not recommend you use first morning urine as it may cause an invalid result.

My test line is visible- but not equal to the control line. Is this a positive?

A positive result is EQUAL TO or DARKER THAN the control line. If you see a result at the test line that is NOT at minimum EQUAL TO the control line, we encourage that you continue testing.

My test is positive, when should I ovulate?

Once you receive a positive, we recommend that you consider yourself in a fertile window and plan intercourse. It is likely that ovulation will take place in the next 24-48 hours.

My test line became positive after the testing time frame, is that a positive?

A positive test result will not change after the testing time frame. However, a negative test result should not be read after 30 minutes. If you are unclear, we recommend that you retest after limiting your liquid intake for 2 hours.

Can I use this test to determine pregnancy?

No, you can not. We encourage that you use our BFP Pregnancy Tests to determine if you have conceived.

My test result is negative – but my other tracking tools show that I am fertile. What’s happening?

To help cover your fertile window, we recommend that you plan intercourse anytime you have a fertile indicator on a tracking tool (like saliva monitoring, cervical fluid, cervix position, etc). Because an ovulation test is urine based and can be subject to dilution, it may not be your first positive sign that you are moving into your fertile window.

I have had multiple days of positives. Why is that?

This is completely normal. You will see a positive result anytime your urine sample has an LH level of 25 miu (the testing level) or more. To not confuse your fertile window, we do not recommend that you continue to test after receiving your first positive result. A positive result indicates that your LH is surging and you are likely to ovulate in 24-48 hours.

Can you use this ovulation kit on women with irregular cycles aswell?

Yes, women with irregular cycles can use these ovulation tests as well, however, they may end up using more tests in one cycle than women with regular cycles.

Is it better to do an ovulation test twice per day as opposed to just once?

The BFP Ovulation Test instructions call for testing once per day; however, some people do elect to test twice per day given that the LH surge can be brief, and factors like urine dilution can impact testing results.

If you elect to test twice per day, try to test at the same times each day (i.e. once in late morning and once in early evening).
