Menstrual changes caused by birth control methods
When you start using birth control pills, your periods will be regulated by the hormones in the pills. This can cause your periods to change. Birth control pills can cause bleeding between periods, and your periods are likely to be lighter or you may not have periods at all. It is very important to take your pills at the same time every day.
The changes caused by the use of progesterone (such as Depo-Provera, Implanon, or mini-pills) are different for every woman. You may have normal periods, bleeding between periods, irregular bleeding, or no periods at all.
Birth Control and the Diaphragm
A diaphragm is a round piece of flexible rubber with a rigid rim. Before intercourse, the diaphragm is placed in the vagina against the cervix. The diaphragm prevents semen from entering the uterus. Spermicide should always be used with a diaphragm for it to be most effective.

Intrauterine devices (IUDs), especially those with hormones, may also cause changes in your periods different than you expected.
When you start using a new birth control method, ask your health professional what you can expect your periods to be like.
