This contraceptive is a 4x4 cm patch that continuously releases the hormones estrogen and a progestin into the bloodstream through your skin. Each patch is worn on the skin for one week, and may be placed on the buttocks, stomach, back or upper arms.
It prevents pregnancy by stopping the ovaries from releasing an egg, thickening the cervical mucus making it harder for sperm to get into the uterus.
The contraceptive ring is a flexible, clear, plastic ring measuring approximately 2 inches (54 mm) in diameter. Inserted into the vagina once a month, it slowly releases two hormones, estrogen and a progestin, into the bloodstream, preventing pregnancy by stopping the ovaries from releasing an egg. It may also thicken the cervical mucus.
The intrauterine device (or IUD) is a T-shaped device that contains a progestin hormone only, which is released slowly over time and acts on the lining of the uterus. Effective for up to 3 or 5 years depending on the IUS, this method makes the lining of the uterus become thinner and the cervical mucus thicker to prevent pregnancy.
Administered by a healthcare professional approximately every 3 months, this injection is given in the muscle of the arm or the buttocks and contains a progestin only. It stops your ovaries from releasing an egg every month, and also thins the lining of the uterus and thickens the mucus in the cervix to prevent pregnancy.
Taken once a day, it’s recommended that you try to take the Pill at the same time each day so that it becomes a habit. Containing two types of hormones, estrogen and a progestin, it works by preventing the ovary from releasing an egg, thickening the cervical mucus making it difficult for the sperm to reach the egg.
The POP pill thickens the mucus inside the cervix to make it harder for sperm to travel to the egg. It also thins the lining of the uterus to prevent the fertilized egg from implanting itself. Like regular birth control pills, it also helps prevent ovulation which is when the ovary releases an egg.
