Hormonal contraceptives are effective for preventing pregnancy, but they come with potential risks and side effects. These may include blood clots, weight gain, headaches, and mood changes. Women who smoke, are over 35, or have certain medical conditions may face higher risks. It’s important to discuss your medical history with your GP, who can help you weigh the benefits and risks, and explore alternative contraceptive methods if necessary. Regular check-ups can also ensure you are monitoring any side effects.
