Before starting to use the microscope for the first time, focus it by rotating the two pieces together until the ♀ symbol on the glass protector seal is displayed. If you do not re-spin the pieces, you'll always have it focused.

Results interpretation

Non-fertile period

If you do not observe ferns, the woman is not ovulating and it will be very difficult to get pregnant

Transition period

If you look at shapes similar to the photo, it is a moment of low probability of conceiving and only before the days before ovulation.

More ferns are observed because the woman is ovulating, it is time to be pregnant

Fertile period
