Despite the claim that home pregnancy tests are effective as little as two to three days before the first day of your next menstrual cycle, the female body does not always live up to this expectation.
The so-called fertile fertility window is when there is the best time to get pregnant and have sex intercourse. It extends for 6 days starting at 5 days before ovulation until the day of ovulation. Your most fertile days are the 1-2 days before and the day of ovulation.
Timing of intercourse is when you try to make love only within a day or 2 of ovulation.
