Can a woman be pregnant if she had her period after nineteen days of delayed menstruation?

No, it is highly unlikely that a woman would be pregnant if she had her period after nineteen days of delayed menstruation. If a woman has a menstrual cycle that is usually 28 days long, and her period arrives 19 days late, it is probable that she is not pregnant. Menstruation is usually a sign of the shedding of the lining of the uterus, which occurs when an egg is not fertilized and implanted. If a woman has her period, it generally indicates that she is not pregnant.
