Ovulation is when a mature egg is released into a fallopian tube where it can be fertilized.
You ovulate (ovulaion) when an egg cell (ovum) matures and is released from your ovary.
An EPT is very accurate, if the hormones hCG is present it will tell you so, if it is not high enough to show pregnancy it will be negative until the level rises. If it is positive you are pregnant, if it is negative wait until your period is 7 days late then try again.
