Can a woman get pregnant within 3 weeks of the last sexual intercourse?

Hi,

How are you doing?

I have gone through your query.

Let me tell you the basics of how pregnancy occurs. In any cycle, ovulation occurs around the 12 to 16th day of periods ( usually ovulation is 14 days before periods, so in a 28-day cycle- ovulation is on Day 14, for a 30-day cycle- ovulation is on Day 16, and so on ). The life of an egg is 24 hours and that of the sperm is 72 hours. So if you had sex within 72 hrs of those 24 hrs of ovulation, sperm would have traveled to tubes and waited there. In the tube the sperm and egg fuse and form the embryo. This embryo stays in a tube for four to five days and then moves onto the uterus and by four to five days the embryo reaches the uterus. This settles and penetrates into the uterus, and starts producing hormones for the baby to fix well, By 14th days after the ovulation or indirectly one to two days after expected periods, these hormones are high enough to be seen on blood tests and in urine too, for the home pregnancy test.

But if you had sex beyond those days of possible ovulation, the chances of pregnancy are very low, as a healthy egg does not meet a healthy sperm.

Hope I have clarified your query, do write back if any more queries.

All the best.

Thanks and regards.
