Various contraceptive methods have their own sets of risks and benefits. For instance, oral contraceptives (birth control pills) can help regulate menstrual cycles, reduce menstrual cramps, and lower the risk of ovarian and endometrial cancers. However, they may also increase the risk of blood clots, especially in smokers and women over 35. Intrauterine devices (IUDs) are highly effective but can cause complications like uterine perforation or infection.
