Hallow Dear, Bear pills are had different types: 1. Monophasic pills are the most frequently prescribed preparations. They contain the two hormones estrogen and progestin, but in a much lower dosage. However, this does not reduce the reliability of contraception.2. Aphasic pills alter the progestin/estrogen ratio in 2 phases. 3. Traffic pills alter the progestin/estrogen ratio in three multi-day phases by varying the amounts of progestin, estrogen, or both. Aphasic and traffic OCS are thought to approximate a women natural hormonal fluctuations more closely by varying the progestin/estrogen ratios. The aim of these formulations is to minimize the occurrence of breakthrough bleeding and amenorrhea while maintaining efficacy. However, some physicians and patients prefer monophasic pills because they are less confusing. You have to consider the pros and cons of these three types and choose one of them whichever suits you. Considering the simplicity of consumption and management, I feel, monophasic pills would suit you better. Yasmin also is a good and reliable birth control pill. I do not understand why you feel that Yasmin is not good product. You may choose anyone from Yasmin and Bear; you will not repent; both are reliable products. Consult your Gynecologist before choosing the type.
