Can I skip my monthly periods with pills?

Q: My periods are going to start from the 21st of this month but I want to skip them with the help of pills as I want to have sex. Is there any harm in doing so?

A:As far as I know, there is no harm in the short term. In fact there is a birth control pill available, which lets you have a period every three months. I am not sure what the implications are for long term. There is no known data, which suggests any immediate interference with pregnancy or your health.
