This will depend on the length of each woman's menstrual cycle. The longer the cycle, the later the daily ovulation tests will be started in order not to waste tests.
For reference, in a 28-day menstrual cycle, the best thing to do is to start the ovulation test about 11 days after menstruation. Calculating accordingly, if the woman has a cycle of 24 days, she can start with the tests at 7 days of the menstruation or, conversely, if the cycle is 32 days, she can start at 15 days of her period.
