Hallow Dear, Belara pills are have different types: 1. Monophasic pills are the most frequently prescribed preparations. They contain the two hormones oestrogen and progestin, but in a much lower dosage. However, this does not reduce the reliability of contraception. 2. Biphasic pills alter the progestin/oestrogen ratio in 2 phases. 3. Triphasic pills alter the progestin/oestrogen ratio in three multi-day phases by varying the amounts of progestin, oestrogen, or both. Biphasic and triphasic OCs are thought to approximate a woman s natural hormonal fluctuations more closely by varying the progestin/oestrogen 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 any one from Yasmin and Belara; you will not repent; both are reliable products. Consult your Gynaecologist before choosing the type. Dr. Nishikant Shrotri
