Normally it is more effective to take the pill before having intercourse so that the hormones are already in your bloodstream, but other than that everybody is different and it can differ greatly.
If you just started the pill your bleeding with probably last however long it did before you started taking the pill. Your next period however will most likely last around 5 days. The pill helps to regulate your period, and it does a great job! But since the first pills you take when you are bleeding are basically placebos your body wont change until you go through almost a whole pack.
It would be best to continue taking the pill each day regardless of bleeding.
When taking birth control pills the bleeding you get each month is withdrawal bleeding and not a "regular" period that comes on its own. So when you miss a few pills the withdrawal from them starts up the bleeding. The steady hormones in the pill keep the uterine lining thin. When you skip the pill for a few days, the pill hormone levels go way down (it takes the body about 24 hrs to eliminate the hormones in one pill). This withdrawal of pill hormones destabilizes the uterine lining and you get spotting/bleeding [thus, the name: withdrawal bleeding].
Missing a birth control pill can result in breakthrough bleeding. As the hormone level in your body drops, bleeding can occur.
When you're on the birth control pill, you have the same protection when you're bleeding and when you're not, as long as you're using the pill as directed.
Some health care provider use the pill to control bleeding on the injection. The bleeding will get better with time.
No, it is a pill for dysfunctional bleeding.
Unscheduled bleeding is common in the first three months of the pill. It gets better with time. Continue taking the pill as scheduled regardless of bleeding.
It's possible that a birth control pill with a different hormone profile could change when your withdrawal bleeding starts.
The first pill does not take effect. Birth control will not prevent pregnancy until you've been on the pill for four weeks.
After taking six weeks of active birth control pills without the pill-free week, you can expect withdrawal bleeding when you take a pill-free week. You may also have unpredictable bleeding.
No; if you took the pill as prescribed, then breakthrough bleeding isn't a sign that the pill is not effective. Breakthrough bleeding is a side effect common in the first three months of pill use.
