Sexual intercourse is necessary for getting pregnant. Some call it "baby dancing," or just "lovemaking," this is the fun part!
In order to get pregnant, you must make love during the 5-6 fertile days, the day of ovulation and the 5 days prior to that day. Even when women have regular menstrual cycles, the exact day of ovulation is often unpredictable. Because you can't exactly predict when you will ovulate and because having sex after ovulation will not get you pregnant, it's best to have sex regularly, throughout the month. Make love regularly, two to three times a week, every week, and make love once every day during your 6 fertile days (day of ovulation and the 5 preceding days).
