[estuapped]

From a Hanafi fiqhi point of view there is nothing wrong in taking the contraceptive pill to defer a menstruation, whether this is at Hajj or any other time or place. It is not recommended though as it can often result in messing up a woman's cycle. Many women take it for Hajj or Umrah and find they have continuous or intermittent istihadha making salah and tawaf very difficult. It also means that many women mess up their normal haydh and istihadha pattern so end up praying when they shouldn't be and vice versa.
