There are two main types of birth control, hormonal and non-hormonal. Hormonal methods work by regulating the woman’s hormones, preventing ovulation, or thinning the lining of the uterus to make it less receptive to fertilized eggs. Non-hormonal approaches, on the other hand, create physical barriers that prevent sperm from reaching an egg. Both types have advantages and potential side effects, so it’s essential for women to explore different options with the guidance of a healthcare professional.
