How to Get Pregnant and How Not to
Fertility is increased when the woman has an orgasm during or after the man. A man, while ejaculating, deposits a pool of semen at the back of the woman's vagina. When a woman orgasms, her cervix pushes forward - dipping itself into this pool several times. The likelihood of sperm entering the uterus through the cervix is therefore increased greatly when the woman orgasms. So, although you don't need an orgasm to get pregnant, it certainly helps, and it makes things a bit more fun, too.
A woman has a fertile time lasting about two days in the middle of her monthly menstrual cycle. The fertile time starts when the woman ovulates (produces an egg) and ends about two days later. The most likely way to get pregnant is to have sex in this fertile time or up to two days before it.
But the problem is accurately identifying this fertile time as it varies from woman to woman and also in individuals. It usually happens about two weeks before the period, but it could be earlier or later. If you want to get pregnant, there are two ways to time sex to coincide with the fertile time. One way is to have sex every day. If you are too tired for this, take your temperature every morning at the same time before you get out of bed and record it carefully. While your temperature will vary slightly from day to day, it will rise sharply by about 0.2 degrees C and stay up at the time of ovulation. That's the time. Enjoy two days of frantic sex. Some women can also feel the time of ovulation by a change in the way they feel inside, or by bleeding slightly.
