GuidesWhich day counts as day 1?
Day 1 is the first day of your period. Count cycle length from the start of one period to the start of the next, then check the chart for your kit. If your cycles vary, check which length the manufacturer advises you to use.
What time of day should I test?
Follow the instructions for your kit, including when to test, how much to drink beforehand and when to read the result. Test strips and digital kits can have different instructions.
What if I never see a positive result?
You may miss a short LH rise between tests. A positive result suggests ovulation may be approaching but does not prove it happened. If results are hard to interpret for several cycles or your periods are very irregular, ask a healthcare professional.
