People who are sexually active, and regularly engage themselves in a sexual act, use contraception as a means for preventing unwanted pregnancy. Condoms and oral contraceptive pills are the two most popular contraception methods among people. Condoms are used during a sexual act by men, while the oral contraceptive pills are supposed to be taken by women on a regular basis. The contraceptive pills are supposed to be taken on a daily basis, and that too on the same time as the previous day. Combination pills are those contraceptive pills, which contain two artificial female hormones, oestrogen and progestogen, as their active ingredients. The mini pills, on the other hand, are contraceptive pills that contain only one artificial female hormone progestogen as its active ingredient.

Combination pills, with the help of the two artificial female hormones, give a three way protection against pregnancy; by tricking your body into believing that ovulation has already occurred, thickening the cervical mucus to prevent sperm from entering the womb, and altering the womb lining in order to prevent an egg from attaching itself to the womb and growing further. Yasmin is one of the most popular contraceptive pills and has been proven to be almost 99% effective in its task. This pill contains ethinylestradiol (oestrogen) and drospirenone (progestogen) as its active ingredients. This pill has now been introduced in a newer version, which is supposed to better than its older version and is known as Beyaz.

Ortho Tri-Cyclen, a combination pill, that is widely used by women, is proven to be very effective in preventing pregnancy. The active ingredients, which help in accomplishing the task, are ethinylestradiol (oestrogen) and norgestimate (progestogen). This birth control pill is most effective if taken on the very first day of your menstrual cycle. If you get delayed on taking the pill on the very first day of your menstrual cycle, then you will be required to take extra contraceptive measures for the next seven days, as it will take another seven days for completely protecting you against pregnancy. Ortho Tri-Cyclen is supposed to be take for all 28 days of your menstrual cycle, and for the last 7 days, you need to take the 7 hormone free tablets that are provided in the pack, during which, you can have your periods.

If you miss a dose of Ortho Tri-Cyclen, it increases the chances of you getting pregnant. If you miss out on any of the active pills, you should take them as soon as you remember. On missing out certain number of pills, you might be required to start a new pack all over again. So it is advisable to contact your doctor if you miss out more than one active pill from your pack.

Some of the side effects that you can experience include sudden numbness, weakness, severe headache, vision problems, coughing up blood, nausea, vomiting, change in appetite, changes in weight, swelling in your breasts, breast tenderness, vaginal itching or discharge and dizziness.
