Wearing the diaphragm or cervical cap longer is not recommended because of the possible risk of toxic shock syndrome. Contraceptive creams, foams, jellies and suppositories Contraceptive creams, foams, jellies and suppositories all contain a chemical spermicide, which prevents pregnancy by killing sperm before they can enter the uterus. In the case of creams, foams, and jellies, you use an applicator to measure out the correct amount, which you insert into the vagina shortly before having sex. If sex is repeated, you must insert another application of foam, cream, or jelly. Some products are available in pre-filled applicators.
Protection lasts for about an hour after the insertion.
Before sex is repeated, you must insert another suppository. Condoms Condoms are available in a variety of styles, and now there is even a condom that can be worn by women. All prevent pregnancy by stopping sperm from entering the vagina. Many women use a condom along with a spermicide for extra protection. If you prefer this method, remember to apply the spermicide into the vagina - not directly on the surface of the condom.
