Ovulation/ fertility date. After menstruation, which normally lasts for 3, 4, 5, days, comes the free period, at this time a woman is free to have sex without protection and pregnancy MAY NOT occur, this period also last for few days, then ovulation, at this period, pregnancy may occur.

Ovulation is when the egg is being released from its follicle waiting to be fertilized by a sperm. If it is fertilized it will be swept up into the Fallopian tube from where it moves into the womb/uterus. If not fertilized, it dies and comes out as what we see as period.
§
A man has two different sex chromosomes, X and Y chromosome, otherwise called hetero-gametic chromosomes, while a woman has two of the same kind chromsomes, X and X chromosome, also called homo-gametic chromosomes.

During ovulation period, a woman is highly fertile, and the first chromosome to meet a woman's fertile egg gets fertilized at the Fallopian tube, from where it moves to the uterus and implants which gives rise to pregnancy. The X -chromosome which gives a female child travels faster than the Y-chromosome which gives a male child. If the X chromosomes of the man fertilizes that of the woman first a female child results.

This is a totally wrong stuff

It's not even the egg that comes out as menstrual period, maybe it's part of it.. But the egg in question (ovum) is so tiny and microscopic at that stage.

When an egg is produced, the uterus lining is thickened in preparation of a pregnancy, so the egg can implant itself to it (uterus).

If no fertilization occur, the lining starts shedding at the next menstrual period ...
