I have been told that women on birth control do not actually release an egg and that the periods she experiences are actually 'fake'. I understand everything about the pill except this one aspect. If the bleeding is not caused an unfertilized egg being released and lining being sloughed off, what causes it? Can you explain the process as simply as possible?

Welcome to ehealthforum.
The periods that you have while being on the pills is usually a withdrawal bleeding. What normally happens is you have the hormones rising up and then coming down if there is no pregnancy resultant in the menstrual cycle. So the hormone levels fall down resulting in the withdrawal bleeding and the sloughing off of the endometrial lining.
When you take the pills, the similar thing happens except for the fact that the egg does not get released from the ovary due to the hormonal levels being higher than in your normal cycles.
Hope this helps.
