By using an ovulation predictor test, by watching for changes in cervical mucus (becomes thin and stretchy, less sticky - resembles uncooked egg whites) by changes in the position of the cervix (drops, opens slightly) and by a slight rise in your temperature - taken as soon as you wake up, before getting out of bed - should be tracked every morning to be accurate.
Most women ovulate anywhere between Day 11 - Day 21 of their cycle, counting from the day they start their period (called day 1).
Ovulation is triggered by a **peak in luteinizing hormone (LH)** secretion.
Peak ovulation only lasts about two days. Buy an ovulation kit to check your ovulation. If a sperm reaches an egg ten days after peak ovulation, well...the egg is probably not there anymore.
That is LH Luteinising hormone.
The ovary would not release the egg, i.e. ovulation would not happen. the egg would not be released into the fallopian tube
At your local drugstore, they should sell over the counter tests to tell you when your ovulation is.

LH and FSH peak to their highest levels during the middle of the menstrual cycle, around day 14, which is known as ovulation.
If you are really concerned then I would suggest using an ovulation prediction kit because they tell you when you could ovulate.
ovulation would not happen
FSH typically peaks around day 14 of a regular 28-day menstrual cycle, which is around the time of ovulation. This peak is responsible for triggering the release of the mature egg from the ovary.
You may be able to find a ovulation calculator in a hospital or some other medical development. Or knowing your body enough you can tell when you are going to ovulate.
On the thirteenth day the level of LH is at its peak, but im not sure what happens after this. Hope this helps.
