Question: is it harder to get pregnant with a 23 day cycle?
Answer: “If your cycle is 35 days long, you're not going to be fertile on day 14 of your cycle. You're more likely to be fertile around days 19 to 25. 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.
