Can I Get Pregnant During My Period?
Yes, it is possible, though less likely. Sperm can survive up to 5 days, so sex during your period can lead to pregnancy if you ovulate early — especially with short or irregular cycles.
How it can happen
If you have a short cycle (say 21–24 days), you might ovulate soon after your period ends. Since sperm can live up to 5 days, sperm from period-time sex can still be present when you ovulate.
Who is at higher risk
- People with short cycles.
- People with irregular cycles where ovulation is unpredictable.
- Those who mistake ovulation spotting for a period.
If you are avoiding pregnancy
Do not rely on timing alone. Use reliable contraception if you do not wish to conceive, since ovulation timing can be hard to predict.
