Clearblue Advanced Digital Ovulation Test, Home LH Ovulation Test Kit, 20 Ct

The Clearblue Advanced Digital Ovulation Test ( Prueba de Ovulacion Advanced Digital Clearblue) typically identifies 4 or more fertile days leading up to, and including the day of ovulation, at least twice as many as any other ovulation test.** The Clearblue Advanced Digital Ovulation Test is a breakthrough: it is the only ovulation test that not only detects the rise in luteinizing hormone (LH), but also monitors the level of another key fertility hormone, estrogen, which increases in the days before the LH surge. Because your partner?s sperm can survive in your body for up to 5 days, you can actually become pregnant by having intercourse during the days leading up to ovulation. If your cycle length varies by more than 3 days, you should use the length of your last cycle to determine when to start testing.
