Yasmin is a low-dose birth control pill. It uses a combination of two hormones progesterone and estrogen to prevent pregnancy. Specifically, Yasmin uses Drospirenone (a form of progesterone) and ethinyl estradiol (a form of estrogen). Yasmin prevents pregnancy in two ways. First, when combined, the two hormones prevent the ovary from releasing an egg. Secondly, in the very unlikely event that you do ovulate, Yasmin has the effect of thickening the uterus lining. This lessens the chances of the sperm ever reaching the egg and fertilizing it.
As with any other birth control pill, the main problem with Yasmin is that you have to be very conscientious about taking it. You need to set a regular time to take the pill so as to maximize its effectiveness and to help you develop the habit of taking it. Missing pills may have dire consequences, depending on the number of pills missed and the week you missed it.
You should also talk to your doctor if you are taking other medication, especially antibiotics. Some antibiotics are known to interfere with the Pills effectiveness. I am sure you wouldnt want to get pregnant just because of an oversight.
