Pros and cons

Pros

Includes both fertility and pregnancy sticks, so compatible Advanced Fertility Monitor owners can use one refill pack for both test types.
The 20 fertility sticks offer a larger supply for cycles that require more testing. The listing says women with irregular or long cycles may need 20 sticks.

Cons

These are monitor-dependent sticks rather than standalone tests, so the required compatible monitor must already be available or purchased separately.
