 What are hormones? Your sex hormones are chemical messengers which instruct various functions connected with your reproductive cycle to start or stop. The combined pill contains two hormones (estrogen and progestogen), both of which are similar to hormones that occur naturally in your body. When you're on the pill, these hormones override the natural ones in your body and take over their work. Natural hormones enable pregnancies, synthetic hormones and pills prevent them.
