Case Study: Natural Contraceptive methods for sexual orgasm
Reader: 12/19/1999>

When is the best timing to have sex to keep from getting pregnant? We have all the children we want and we do not want to have surgery.

Dr. Lin:12/19/1999>
You can use natural methods to achieve Contraception. We have done it since we were young.

1. Clock her menstrual cycle. The following graph is a typical 29-day period.
Her period may be different, 26, 27, 28 or 30 days.
Women on heavy soy diet with light red meat and dairy products will have a little longer period.
2. The ovulation day is in the middle of the menstrual cycling, where 2 days around it requires heavy contraception with condom + water-based spermicide jelly.
3. Allow 3 days for sperm and egg to survive and for counting the uncertainty error of the menstrual cyclin.
4. Thus, the conceptive period is about 7 days in the middle of the menstrual cycle, during which, excluding the ovualtion day (I prefer counting 2 days), you can use spermicide jelly. The safest way is to conside the conceptive period to be 8 or 9 days.
5. It is not neccessary to have contraception for the rest of the days.
