When conception occurs the embryo needs the uterine lining to protect it and to build a placenta on. When the egg goes unfertilized the lining is discharged (menstruation) and a new lining starts fresh every month.
Menstruation typically occurs about 14 days after ovulation.

No, the egg isn't released during menstruation. The egg is released during ovulation, which typically occurs two weeks before menstruation, if the egg isn't fertilised then this leads to menstruation.
Menstruation is a monthly cycle that occurs in females. When an egg is not fertilized, it passes out of the woman's body in the form of blood. Ovulation occurs mid-cycle, and it is the release of an egg from one of the ovaries.

28 days
If a woman menstruates, whether she is a teen or an adult, then she can't possibly be pregnant. Menstruation only occurs if the egg released during ovulation hasn't been fertilised.
Menstruation occurs at the start of the menstrual cycle and normally lasts around a week, so menstruation would occur days 1-7 of the menstrual cycle.
