Not due to the drug. Misoprostol is not reported to cause amenorrhoea. You had an unusual menstrual cycle. However, unusual menstrual cycles don't necessarily mean that there's anything wrong physically. The menstrual cycle is under very delicate hormonal control, which can be influenced by things such as exercise, rapid weight change, emotional stress etc. SEE: http:///bit.ly/19cKee5 See Dr if doesn't return to norma.
