It should be the same amount of time as when NOT on birth control.
The only way you can delay menstruation is by taking birth control pills.
There is no "follicular phase of menstruation" when you're on hormonal birth control.
Birth control inhibits fertilization, not menstruation. Menstrual cycle will still continue.
The withdrawal bleeding is not regular menstruation. Birth control changes the hormones in your body and suppresses ovulation, therefore there's no egg that was released to cause menstruation. That's why birth control prevents pregnancy.
Birth control pills help . Otherwise there isn't much to do.
When the uterine lining sheds this is typically called menstruation. Although women on hormonal birth control will experience a faux period in the form of a withdrawal bleed.
THere is no limit. You can take it as long as you like, and as long as no new health concerns crop up that might make it a bad choice.
Besides hormonal birth control the only real options to stop menstruation would either be to get pregnant or to have a hysterectomy.
If there are no other problems, and the bleeding is due to hormonal imbalances, birth control pills are often prescribed to bring the bleeding under control and regulate menstruation.
Over time the pill regulates it and can make it shorter and lighter. Once you stop the birth control pill, you can expect to go back to your previous menstrual pattern.
In theory, anytime after menstruation has begun.
Menstruation and you are fertile again, everything back to normal.
