Periods stop almost immediately upon becoming pregnant, not in any specific month.
When a woman becomes pregnant, her body undergoes hormonal changes that prevent ovulation and, therefore, menstruation. According to the provided reference, "Menstruation only occurs when a person is not pregnant." The absence of a period is often one of the first signs of pregnancy.
- No Ovulation: Pregnancy hormones halt the release of eggs.
- No Shedding of Uterine Lining: The uterine lining is maintained to support the developing embryo.
- Implantation Bleeding: Some women may experience light spotting around the time of implantation, but this is not a period.
