Fetal Development

Your uterine lining (endometrium) is thickening as the ovary is preparing to release one of your eggs (2 if you are preparing to have twins!) into the fallopian tubes that leads to your uterus.

Estrogen hormone levels increase, as a result the cervix starts to produce cervial mucus. This jelly like substance fills the opening of the cervix and lines the uterus and fallopian tubes, assisting the sperm in swimming up to the fallopian tubes, in readiness for when an egg is released. The mucus is an essential element to conception due to it's ability to keep a man's sperm alive for up to 3 to 5 days in a woman's body.

The timing of intercourse if you're trying to conceive can be difficult. Sperm can live for 3 to 5 days, but the egg or ovum is only around for 24 hours. However, studies have found that the fertile period starts 5 days before ovulation and ends on the day of ovulation, with conception most likely to occur if intercourse happens 2 days prior to ovulation. That way, the sperm is already waiting for the egg in the fallopian tubes.

Because of all the hormonal changes in a woman's body, ovulation can be accurately predicted, and intercourse timed accordingly. To read more about the different methods of ovulation prediction, visit Ovulation Calendar.
