Track your LH surge with ovulation test strips and compare the test and control lines within the stated reading window.
Use pregnancy test strips to check your result and know when to repeat testing if the line is faint or unclear.
Track small temperature changes across your cycle with a basal body thermometer and support ovulation charting over time.
Use midstream ovulation tests to identify your LH surge, read the result within the stated window, and test with confidence at home or on the go.
Use midstream pregnancy tests to check your result within the stated reading window and know when to retest if the line is faint or unclear.

Line reading support
Fast answers to common questions about ovulation tests, pregnancy tests, faint lines and reading results correctly.
Compare your test with the examples below, then check what the result means and what to do next.
Both lines are present. The test line is as dark as or darker than the control line.
T line as dark as or darker than C line
LH surge detected. Ovulation is likely within the next 12 to 48 hours.
The control line is dark, and a second coloured line is visible in the test area, whether faint or darker.
Faint or darker pink line
Pregnancy hormone is likely present. If the second coloured line appears within the stated reading time, treat the result as positive. If you tested early or are unsure, test again in 48 hours.
The control line is missing. The result is invalid.
No control line
An invalid test can happen if the test is dipped past the MAX line or not held in urine for long enough. Retest with a new test.
The control line is dark and no coloured test line appears within the stated reading time. A thin grey or colourless mark that appears only after that time may be an evaporation line and should be ignored.
Late grey or colourless line
This is a negative result. Ignore any line that appears after the stated reading time, because only a result read within that time counts. On pink-dye tests, a valid positive line has colour. If you tested early or are unsure, test again in 48 hours.
Read results only within the stated reading time. T = test line. C = control line. MAX = maximum dip line.
Use the information below if your result still does not make sense or your timing is hard to work out.
You may have started testing too late in the cycle or based your timing on a longer cycle than usual. Next cycle, start from your shorter recent cycle pattern so you are less likely to miss an earlier surge.
Common mistakes include reading the result too late, using very diluted urine, dipping past the MAX line, or missing the timing steps for your test. For midstream tests, follow the hold time exactly.
If the result is negative but your period is late or the result is unclear, test again in 48 hours using the instructions for your product.
Some LH surges are brief and easy to miss. If your line changes quickly or never becomes clearly positive, consider testing twice daily near your expected fertile window, and look at the full pattern across the cycle rather than relying on a single test.
If your cycles are very irregular, you do not see a clear surge over more than one cycle, or your results remain confusing, speak with your GP in Australia.
Yes. Drinking a lot of fluid before testing can make the result harder to read, especially if the line is faint. Follow the instructions for your product and avoid over-hydrating before the test.
Ovulation calculator
Use our ovulation calculator to estimate when to begin ovulation testing based on the first day of your last period and your average cycle length. Estimates only. Ovulation can vary from cycle to cycle.
Estimate your fertile window and plan when to start ovulation testing. Enter the first day of your last period and your usual cycle length.
This calculator provides a date estimate only and cannot confirm ovulation.
Base your start date on your shorter recent cycles so you are less likely to miss an earlier LH surge. If your cycle length changes a lot, use the estimate as a guide rather than a fixed rule.
Try to test at a similar time each day. Late afternoon or early evening often works well. Avoid excess fluids beforehand to make the result easier to read.
Start earlier next cycle and consider testing twice daily around your expected fertile window. If results stay confusing over more than one cycle, speak with your GP in Australia.
Timing context
These situations can make ovulation and pregnancy testing harder to time or interpret. Use the information below as a starting point, then follow your product instructions.
PCOS can cause irregular periods and less predictable ovulation, which can make test timing and LH patterns harder to interpret. If you see more than one rise or no clear peak, look at the full-cycle pattern rather than a single test.
If your cycle length changes from month to month, base your timing on your shorter recent cycles and use date estimates as a guide rather than a fixed rule.
After stopping the pill or other hormonal contraception, it can take time for your cycle to settle. Start earlier rather than later and treat the first few cycles as a guide, not a fixed pattern.
If you work night shifts, test at the same point in your routine each day rather than by the clock alone. For ovulation test strips, follow the product leaflet: avoid first morning urine, collect urine between 10am and 8pm at about the same time each day, and reduce fluids for about two hours beforehand. For basal body temperature, measure straight after waking, before you get out of bed. Changes in sleep can affect your temperature readings.
If you are using fertility treatment, follow your clinic's advice first. Some treatments can change when ovulation happens or how home test results should be interpreted.
After pregnancy, especially if you are breastfeeding, your cycle and ovulation timing can be harder to predict. Start earlier rather than later and use date estimates as a guide, not a fixed rule.
Testing questions
These answers cover common questions about test timing, result accuracy and what to do next if your results are unclear.
Start from your shorter recent cycles so you are less likely to miss an earlier LH surge. If your cycle length changes a lot, use our ovulation calculator and your recent cycle pattern as a guide rather than a fixed rule.
Not usually. Many people find ovulation tests easier to use later in the day. Try to test at a similar time each day and avoid excess fluids beforehand.
You can test from the day your period is due. If you test earlier, the result may be faint or negative even if pregnancy has started. If you are unsure, test again in 48 hours.
Both can be accurate when used correctly. The main differences are format, convenience and how easy the result is to handle and read.
Yes. You may miss a short LH surge, start testing too late, or have timing that is harder to detect with home tests alone. If this keeps happening, look at your full cycle pattern rather than a single result.
Go back to the instructions for your exact product, check your timing, and repeat the test if needed. If your results stay confusing over more than one cycle, speak with your GP in Australia.
If your result still does not make sense, go back to the relevant product guide above, then read the articles below for more detail on faint lines, negative results, fertile timing and evaporation lines.
If your result does not match the instructions, you read the test outside the stated window, or your cycle is hard to track, check the relevant guide again first. If you still need help, contact us by email.
If your cycles are very irregular, your results remain confusing across more than one cycle, or you have been trying to conceive without success for 12 months (under 35) or 6 months (35 or older), speak with your GP in Australia.
