Question: can you get pregnant on day 7 of a 23 day cycle?
Answer: If you have a shorter cycle – for example, 23 days – you might ovulate around days 7 to 13." Sperm can survive in a woman's body for several days after sex. If you want to get pregnant, having sex every couple of days will mean there are always sperm waiting in the fallopian tubes to meet the egg when it's released.
