Is she taking the Ortho-Tri-Cyclen for a specific reason other than for birth control?
Here is something I found, I hope it helps:
Birth Control You Need to See Your Doctor For
The risks and benefits of different forms of birth control are different for each person. So it's best to decide with your doctor which form of birth control is best for you.
Diaphragm
The diaphragm with spermicide is put into the vagina before sex so that it covers the cervix, or neck of the womb. Put the spermicide into the dome of the diaphragm before inserting it. You must be fitted for a diaphragm at a doctor's office or clinic because diaphragms come in several different sizes. The diaphragm must stay in place at least 6 hours after intercourse, but not for more than 24 hours. If you have sex more than once while wearing the diaphragm, you must add more spermicide without taking the diaphragm out. Spermicide is available without a prescription at drugstores.
Cervical Cap
The cervical cap is a soft rubber cup with a round rim that is put into the vagina to fit over the cervix, or neck of the womb. The cap is smaller than the diaphragm, but sometimes more difficult to insert. You must go to your doctor or clinic to be fitted for the cervical cap. It comes in several different sizes. The cervical cap must be used with spermicide, which is available in drugstores without a prescription. You can leave it in place for 48 hours.
Birth Control Pills
You need a doctor's prescription to get birth control pills, also called oral contraceptives. There are two types of birth control pills: "combined oral contraceptives" and "minipills."
Combined oral contraceptives have a combination of two hormones--estrogen and progestin. They work by keeping the ovaries from releasing an egg. The pill must be taken every day.
Minipills contain only one hormone, progestin. They work by thickening the cervical mucus to keep sperm from reaching the egg. Sometimes they also keep the ovaries from releasing an egg. You must take one pill every day. Minipills are slightly less effective than combined oral contraceptives.
Depo-Provera
Depo-Provera is a form of progestin, similar to the hormone in the minipill. Depo-Provera must be injected with a needle into the woman's buttocks or arm muscle by a doctor. You must get an injection every three months for the birth control to continue to work.
Norplant
Norplant is a form of progestin that is placed under the skin. Norplant is made of rubber rods that look like matchsticks. A doctor places the rods under the skin of the woman's upper arm, where they slowly release progestin. A doctor must also remove the rods. There are two types of Norplant. The six-rod Norplant gives birth control for up to five years. The two-rod Norplant gives birth control for up to two years.
IUDs
An IUD (Intrauterine Device) is inserted into the womb by a doctor. Two types of IUDs are now used in the United States: the Paragard Copper T 380A, which releases copper, and the Progestasert Progesterone T, which releases progesterone, a form of progestin. The Paragard IUD can stay in place for 10 years. The Progestasert must be replaced every year. A doctor must remove it.
Male Sterilization (Vasectomy)
Outpatient surgery is necessary to make a man sterile, or unable to produce enough sperm to make a woman pregnant. This is done by sealing, tying or cutting the tube through which sperm travel to the penis from the testicles. The operation usually takes less than 30 minutes and is done under local anesthesia. Men who have vasectomies must be sure they will never want to father children in the future.
Female Sterilization Female sterilization is usually a longer operation than a vasectomy, though it may sometimes be done as outpatient surgery. It is usually done under general anesthesia. The surgery involves tying, cutting or blocking the fallopian tubes so eggs can't reach the womb. Women who have this surgery must be sure they will never want to have a baby in the future.
Good luck,
