The only way to garauntee that you don't get pregnant is to not have sex at all.

levonorgeatrel is a 1st generation synthetic version of the hormone Progesterone - desogestrel is a 3rd generation and supposed to carry less side effects like Acne, unwanted hair growth and weight gain however proven to give a higher risk of Thrombosis!

According to http://www.drugs.com/mtm/solia.html, Solia and Reclipsen are two different brand names for the same generic drug ethinyl estradiol and desogestrel. So it would appear that there is no medically functional difference between the two.

Ethinyl estradiol and desogestrel contains a combination of female hormones that prevent ovulation (the release of an egg from an ovary). This medication also causes changes in your cervical mucus and uterine lining, making it harder for sperm to reach the uterus and harder for a fertilized egg to attach to the uterus.
