Understanding Female Fertility: Days of Fertility in Your Cycle

Question
how many days a woman is fertile in a month/per cycle?
is a woman fertile several days before, during and several days after ovulation?
thanks

Answer
A particular woman's fertility cycle depends totally upon the woman and how her body works.

Pregnacy is the result of the man's particular fertility (sperm count and sperm motility) working with that particular woman's fertility.
