How Long Does It Take For Birth Control to Work?

Birth control pills are the most common form of birth control for women and they are usually taken during a 28 or 21-day period. The purpose of these pills is to control your ovulation and prevent unwanted pregnancies. The birth control pill contains two types of hormones that keep ovulation from happening. Estrogen and progesterone are the hormones this pill has and they work together to stop egg fertilization in a woman’s body. It also allows the blocking of sperm in the woman’s body and this is good for couples who want to delay parenthood for a few years. If you do not take the pill consistently, pregnancy could happen.

How Long Does It Take for Birth Control to Work?

It will be at least a week before birth control will work properly in your body and this is why it is important to not skip days when taking birth control. If you take emergency contraceptives that are known as “morning after pills”, it can take a day or two before ovulation stops temporarily after you had unprotected sex. However, some medical experts say this is not the best form of birth control and could cause problems with menstruation. If you use a condom, you will get immediate results although condoms are not 100% effective in stopping a pregnancy because condoms come off during intercourse at times and someone could punch a hole in the condom. If you prefer the birth control patch, it is best to start using it on the first day of your period.

Remembering to Take Birth Control Pills

One way to remember to take your birth control pills is to take your second pack of pills on the same date you began the first pack. Another idea is to take your pills at the same time every day so that the pills can work effectively. If you forget to take a pill and you are getting ready to have sex, you can use a condom or take an emergency contraceptive if you already had sex.

A Word About Condoms As Birth Control

When you use lubricants with condoms, never use oil-based lubricants because they will make it easy for condoms to break. Instead you should only use water-based lubricants. You should never store condoms in a warm place because doing that decreases the effectiveness of the condom. If you have sex often, you should purchase one to two boxes and keep a few on you whenever you go out. When ejaculation takes place, always wear a new condom.


Birth control comes in many forms and the safest form of birth control is abstinence. For those who continue to have sex and want to avoid pregnancy, you should take birth control pills or use a birth control patch to prevent pregnancy. Talk with your gynecologist to determine which birth control treatment would work the best for you.
