Yes, it's possible, although unlikely. Pregnancy during menstruation is possible due to variations in ovulation cycles and the lifespan of sperm.
Understanding the Menstrual Cycle and Ovulation
The menstrual cycle is a complex process. While bleeding typically signals the end of a cycle, not the beginning, the timing of ovulation (when an egg is released) varies significantly between individuals. Some women may ovulate earlier or later than expected, even during menstruation. Sperm can survive inside the female reproductive tract for several days, increasing the chance of fertilization even if intercourse occurs before ovulation.
Factors Affecting the Likelihood of Pregnancy During Menstruation
Several factors influence the chances of conception during menstruation:
- Ovulation timing: The most fertile period is usually around ovulation, which typically occurs about 12-14 days before the next menstrual period. However, variations are common.
- Menstrual cycle length: Irregular cycles make it harder to predict ovulation, thus increasing the chances of conception during or immediately after menstruation.
- Sperm survival: Sperm can remain viable for several days within the female reproductive system. If intercourse occurs just before or during the start of menstruation and ovulation occurs a few days later, pregnancy is possible.

- Planned Parenthood: Explicitly states that pregnancy is possible during a period, though uncommon. (https://www.plannedparenthood.org/blog/can-you-get-pregnant-if-you-have-sex-during-your-period)
- American Pregnancy Association: Acknowledges the statistical possibility due to variable ovulation cycles. (https://americanpregnancy.org/can-i-get-pregnant-if/can-you-get-pregnant-on-your-period/)

- KidsHealth: Explains the possibility, linking it to the variability of ovulation. (https://kidshealth.org/en/teens/sex-during-period.html)
In conclusion: While not common, pregnancy during menstruation is possible due to the variability of individual menstrual cycles and sperm viability.
