How to induce menstrual cycle?missed cycle for the first time last december.not pregnant

MIssed Periods: You do nothing, as you have already been advised. These things happen and usually you will start up during the next month. One does not 'induce' a period that has been missed. If you do not restart cycling then you contact your gynecologist for an evaluation.

Progesterone: It is not unusual to miss a cycle once a year, but you can have a withdrawal bleed by using Progesterone . See a provider for guidance.
