It is unusual for a woman to become pregnant so soon after her menstruation has ended. Pregnancy is significantly less common in the first week following a woman’s period than in the first few days or weeks of the menstrual cycle.
A woman can become pregnant at any moment throughout her menstrual cycle if she engages in sexual contact without taking contraception, including during and immediately after her period. Women are most fertile and thus most likely to become pregnant at specific points of the menstrual cycle.
Three to five days after your cycle has ended are fertile days. The risk of becoming pregnant soon after your period is determined by several factors, including the duration of your menstrual cycle and the length of your period. Fertile days can start as soon as a few days after menstruation ends in women who have long periods.
Ovulation can occur within a few days of the end of the period in women with short menstrual cycles, such as 22 days. Sperm can survive in the viable cervical mucus for up to seven days. Given this, it has been proposed that women who ovulate sooner than usual may have a higher probability of becoming pregnant.
If a woman’s cycle is unpredictable, she may become pregnant shortly after her menstruation finishes.
