A woman is most fertile around ovulation, when an egg is released from the ovaries. If the woman has a normal 28-day menstrual cycle, the ovulation would occur approximately 12-14 days before the start of her next period. A woman is most likely to get pregnant if she has sex 1-2 days either side of when she is expected to ovulate. However, sperm can survive in the body for up to 7 days, so it is possible to get pregnant if you have sex up to a week before ovulation.
A woman is most fertile during ovulation, approximately 12-14 days before the start of her next period. However, if you are trying to get pregnant, you do not need to have sex at exactly this time, because sperm can survive for up to 7 days inside the body. Instead, it is recommended that you have sex every 2-3 days, to give yourself the best chances of conceiving.
It can be difficult to tell if you are ovulating, but there are various signs you can look out for:
If it is 12-14 days before your next period, it is likely you will be ovulating.
You may experience a small increase in your body temperature, which you may be able to detect with a thermometer.
The mucus around your cervix and vagina may become wetter, clearer or more slippery during ovulation.
Ovulation predictor kits which measure hormone levels in your urine, can reliably tell you when you are most likely to ovulate.
Natural family planning is a contraceptive practice that uses the menstrual cycle of a woman to estimate her fertility over the month. This can be used to try to prevent pregnancy, but it is not as reliable as other birth control methods. Due to the individual differences and other factors, the typical effectiveness of this approach to contraception is only 76%.The approach involves calculating when a woman is expected to ovulate so that sex can be avoided during that period. As it is difficult to predict the exact date of ovulation and sperm can survive for up to 7 days in the female body, this natural method of contraception can be unreliable. However, many people choose to use this method for religious reasons, when they do not wish to use other forms of contraception.
