A 21-year-old female asked:

what are some side effects from switching birth control brands? do you have to get your period before starting the new brand?

Switch uninterrupted: If you will be using the same method (oral contraceptives), you can switch brands without interrupting pill schedule. However, if you will be transitioning from pills to iud, patch, etc you will need to use back-up method and discuss timing issues with your gynecologist (each has different protocols..).

Changes in flow: Changes in flow can result from changing from one bcp to another; other examples might be either an increase or decrease in:quantity, length in days, facial acne, & cramping . It is not necessary to wait for a new period to change from one pill to another although the symptoms or changes may occur more readily.

Not your periods: Both menses sound normal being moody is likely related to other circumstances (husband, kids, job, money ?).

When spotting very little, is it considered a menstral cycle?

Dr. Michael Swor

Hypomenorrhea: Very light menstrual flow can be normal. Having regular cycles that aren't too heavy or painful is more important than concern about enough flow. A sudden change in menstrual flow can signal a problem, like a hormonal change or pregnancy.
A 31-year-old member asked:

Can anybody tell me how well the rhythm method works as a birth control?

1 doctor answer6 doctors weighed in
Dr. Timothy Brown
Obstetrics and Gynecology 44 years experience
Not very reliable: Using the rhythm method effectively depends upon absolutely regular and predictable cycles (not common) and considerable self-discipline. Since your sexual desire or libido increases when you are most fertile and this is exactly the time you have to avoid with the rhythm method, it tends not to work out well.
