You're most fertile at the time of ovulation (when an egg is released from your ovaries), which usually occurs 12 to 14 days before your next period starts. This is the time of the month when you're most likely to get pregnant. It's unlikely that you'll get pregnant just after your period, although it can happen.

How many days after my period can I get pregnant?

The safest time is six or more days before ovulation, where the chance that a woman will get pregnant is virtually zero. These are the days of your period and a few days after the period. So whilst you can technically pregnant three days after your period, it is less likely on this day of your cycle.

What are possible days of conception?

Conception (when the egg is fertilized by the sperm) can take place as soon as three minutes after sex or it may take up to five days. Implantation (when the fertilized egg attaches to the uterine wall) occurs five to 10 days after fertilization—which means it can happen anywhere from five to 15 days after you had sex.
