Can you get pregnant on your period
There are lower chances of getting pregnant if you have intercourse on your period. However, if the length of your menstrual cycle is short, it is still possible to get pregnant. This is because the amount of time between your period and your ovulation is shorter. Additionally, the fact that sperm can survive in your reproductive tract for up to 72 hours is a contributing factor as well.
It is less likely but still possible to get pregnant if you have intercourse during your period. If you ovulate earlier than the average time, and have intercourse towards the end of your period then, the chances are that you may conceive four or five days later. That’s because sperm can live inside you for up to three days in the right environment.
If you’ve heard someone say that they conceived on the first day of their period, and wondered if that’s even possible, the answer is yes, it's possible. Although it’s not very likely, especially for those who have a 28-day cycle. For conception to occur on the first day of a period, a woman would probably have an irregular or a shorter menstrual cycle, wherein ovulation might occur much closer to day one of your period, which could lead to conception.
