Other options include taking higher-level hormones every day to block your period for a year.

BCPs can give you more control over when your periods happen. Extended-cycle pills can help you avoid your period during important events such as a planned vacation.

But even with extended-cycle pills, it can take several months for your hormones to level out. You may experience some bleeding or spotting during the first few months that you take this type of pill.

Implant birth control

This method must be inserted into your body by your doctor. A small implantable rod can be placed under the skin on your upper arm where it releases hormones to prevent pregnancy. The rod is about the size of a match and is flexible.

Because the rod is a type of hormonal birth control, it may cause changes in your period. Some women have heavier or longer periods, while others have lighter periods, or no periods at all.)(3)

Intrauterine devices or IUDs are T-shaped implants that are placed by your doctor in the lining of your uterus. There are two basic types: copper and hormonal.

Copper IUDs release the mineral copper which interferes with sperm reaching an egg. If the egg does become fertilized, the IUD prevents the egg from implanting in the wall of uterus.

Copper IUDs may result in heavier than normal bleeding with your monthly period, and may cause increased cramping. These changes may decline approximately six months after you receive your IUD. A copper IUD should be replaced after about 10 years. (4)

Hormonal IUDs release progestin into the uterus to prevent pregnancy. These IUDs are more likely to cause your period to be lighter and less painful over time. Hormonal IUDs must be replaced every three to five years. (4)


This method blocks the fallopian tubes or surgically cuts or ties the fallopian tubes to prevent sperm and eggs from meeting. This non-hormonal method does not affect your period.
