The womb is getting itself ready to welcome the embryo and as the lining thickens, the mucus in the cervix becomes thinner to enable the sperm to swim through it easily. It is very possible that you may have ovulated approximately on the last day of this week or the beginning of the next.
Ovulation occurs when the follicle ruptures and releases an egg or ovum, which is approximately 0.13 mm in size. This egg travels up the fallopian tube and survives for about 24 hours. This is your highly fertile period. If the egg is not fertilized within this time, it passes out the next time you menstruate. Which fortunately did not happen in your case.
