Optimising timing for pregnancy
To improve the chances of becoming pregnant, timing intercourse around ovulation is key. Having sex daily, or at least every second day, in the days leading up to ovulation increases the likelihood of sperm being present when the egg is released. When an ovulation predictor kit shows a positive result—indicating a surge in luteinizing hormone (LH)—this signals peak fertility and is an especially good time to have intercourse.
Ovulation predictor kits can be used at home and work by detecting LH in the urine. It’s recommended to begin testing a few days before you expect ovulation, based on your usual cycle pattern.
You may also notice physical signs that ovulation is approaching. Cervical mucus often becomes clear, slippery, and stretchy in the days beforehand, which helps sperm travel more easily.
Ovulation is when an ovary releases an egg, typically around the middle of the cycle, about day 14 in a 28-day cycle, though this can vary, as cycle lengths commonly range from 25 to 35 days.
For pregnancy to occur, several conditions need to be in place: a healthy egg, healthy sperm, open fallopian tubes, and a normal uterus.
