We were married 1 year ago. We never wanted children so took care and precautions while having sex. Every month her menstrual cycle is good. We are going to a devotional tour for 5 days from 25th February to 1st March. But the problem is that she's not having menses till now. Her menstruation date is 17th. But she's not. So She decided to use medicine. But she's in confusion that whether to use medicine to have menses. Or wait until 25th and use medicine to stop menses for 5 days. I request please mention medicine for both the conditions with dosage along with your suggestions. Tablets to have menses.? Immediately Tablets to stop menses. For 5 days.
