Fertility Awareness Methods FAM=methods of contraception that involve determining the fertile days of the female’s menstrual cycle, and avoiding intercourse those days These methods are about 80% effective Teen’s menstruation cycle is irregular, less easy to predict Basal Body Temp Method- Uses body temperature to measure ovulation Cervical Mucus Method- Checking the mucus levels, clear, stringy, slippery means ovulation is nearing Once ovulation is determined to be near the couple will refrain from sexual intercourse for 6-7 days before and 3 days after ovulation Menstrual Cycle must be regulated, no protection against STD’s

Barrier Methods Barrier methods are devices that prevent the sperm from reaching the egg either physically or chemically. Male Condom- a thin sheath of latex, plastic, or animal tissue that is placed on the erect penis to catch semen. Some are coated with spermicides. Female Condom- a polyurethane pouch that fits inside the vagina. *No petroleum based products should be used with condoms *No heat, especially when storing

The Diaphragm and Cervical Cap Have to be obtained through prescription Diaphragm- a soft latex or silicone cup with a flexible rim that covers the entrance to the cervix Must be placed in before sexual activity and left in for 6 hours after, but no more than 24 If sexual intercourse occurs again must reapply spermicides without removing Cervical Cap-a thimble-shaped, soft latex cup that fits snugly over the cervix. Spermicides are applied to both sides before insertion. Must be filled 1/3 with spermicides, Stay in at least 6 hours after, but not more than 48 Both come in different sizes, so a pelvic exam is required Must be resized after birth, weight gain, weight loss

Spermicides Foams, Jellies, Creams, and Tablets are non-prescription forms of birth control that contain spermicides Usually applied using an applicator deep into the vagina near the cervix To be affective must be applied 5 to 90 minutes before intercourse Must remain in place from 6-8 hours after, do not wash

Vaginal Contraceptive Ring Prescribed by the doctor Releases estrogen and progestin to stop ovulation A flexible ring that is placed in the vagina for three weeks and then removed during menstruation Must be in place for 7 consecutive days If removed more than 3 hours then another form of contraception should be used
