- Please always read the instructions on pack and in the leaflet carefully before use.
- You need to know your usual cycle length before you start, to ensure you test at the right time to find your LH surge
- To determine your cycle length, count the day period starts (first day of full menstrual flow) as Day 1, and continue counting through to the day BEFORE your next period starts – the number of days is your cycle length.
- Once you know your cycle length, use the table below to find out when to start testing:
|Your cycle length in days||21 or less||22||23||24||25||26||27||28||29||30||31||32||33||34||35||36||37||38||39||40||41 or more|
|Start testing on the day next to your cycle length||5||5||6||7||8||9||10||11||12||13||14||15||16||17||18||19||20||21||22||23||17 days before your next period|
- You can test at any time of the day, but you should test at the same time of day each day.
- Try not to urinate for four hours before you do the ovulation test, and you should avoid excessive fluid intake before testing – you might find it easier to use the first urine of the day.
