As I stated in my previous answer to you, the ovulation predictor tests do not confirm that you've ovulated. If the pregnancy test was negative, then you should repeat the pregnancy test in a couple of days to be sure you are not pregnant. The embryo has to be of sufficient gestational size to register sufficient hCG for a home pregnancy test to pick it up in the urine.
The simplest way to know when you are most fertile and when you are ovulating is to use an ovulation calculator. What was the first day of your last menstrual period? How long are your menstrual periods?
Ovulation usually takes place 14 days after the beginning of your menstrual cycle. An egg is capable of being fertilized for 12 to 48 hours before it begins to disintegrate. This is the most fertile period of your cycle. The exact time of ovulation may vary within your cycle because ovulation can be delayed by stress, illness, diet, or increased physical activity.
Your fertile period starts about 4-5 days before ovulation, and ends about 24-48 hours after it. This is because sperm can live in your body for approximately 4 to 5 days, and the egg can live for 24 to 48 hours after being released. You are most fertile on the day before and the day of ovulation.
