How long will menstruation delay if you take contraceptives?

After oral contraceptives, menstruation will be delayed for 5-7 days. Because women's body sensitivity to hormones is not the same, so the time delayed menstruation is not the same. Suggestions: women need a positive rest after oral contraceptives, maintain a good mentality, do not drink alcohol, smoking, so as not to affect the efficacy of contraceptives.
