Female Contraceptive Pill: How Fast Do They Work To Prevent Pregnancy

How fast do birth control pills actually work? This is a very obvious and important question to ask if you are worried about a possible unwanted pregnancy to occur. It is a very traumatizing situation for someone who does not want an unwanted pregnancy. After all, it is about avoiding the pregnancy as soon as possible. Be it an unprotected sexual intercourse or some other accidental way, unwanted pregnancies can give you quite the nightmares. Female contraceptive pills have become one of the most popular methods of birth control. In fact, they paved the way to planned parenthood. But, how fast do they actually work? The answer to this question is not totally straight-forward as there are a lot of factors on which it depends.

Are All Birth Control Pills Similar?
Before answering this question, it is important to know that there are actually two types of birth control pills. The two types of birth control pills or oral contraceptives are:
1.Combination birth control pills.
2.Progestin-only or mini birth control pills. As the name suggests, combination pills contain a combination of two hormones, namely, estrogen and progestin. Whereas, Progestin-only contain only progestin and are often called the mini-pill.
How Do These Female Contraceptive Pill Work?
When it comes to combination birth control pills, they work mainly by suppressing ovulation. In simple words, they prevent the release of an egg and avoid fertilization. So, when no fertilization occurs, there cannot be a situation of pregnancy. The cervical mucus is also thickened by the combination birth control pills so that it is difficult for sperm to pass through. It also thins down the lining of the uterus. A thinner lining of the uterus makes the attachment of the fertilized egg to it very difficult thus, avoiding pregnancy.
On the other hand, Progestin-only or mini-pills suppresses ovulation in near about half the users. The main job of the progestin-only birth control pill is to thicken the cervical mucus to make it difficult for sperm to pass through and reach the egg. Apart from this, it thins the uterine lining as well like the combination pill. This makes it very difficult for the fertilized egg to embed.
Are These Birth Control Pills Safe?

How fast do these Birth Control Pills Work?
When it comes to combination pills, it is all about when you start off your first pack. When taken on the first day of your period, they start working right away in preventing pregnancy. It is important to give the pill 7 days before it starts protecting against pregnancies, if taken at any time after your period. It is very important to use condoms during that time.
On the other hand, Progestin-only pills can be taken at any time during the menstrual cycle. However, it takes 48 hours for the progestin-only or mini-pill to take effect after you start it. So, during that time it is necessary to have back up method if sexual intercourse takes place. It is important to note that the mini-pill has a lower dose of hormones when compared to the combination pill. So, the effects fade away after 24 hours. This is the reason that you need to take them at the same time every day for them to work effectively in preventing pregnancy. In case you are late in taking it or miss it, a back-up contraception should be kept ready for those 48 hours again.
