Birth control pills are a common and effective way to prevent pregnancy. However, many factors can affect the final results. For example, missing pill days, vomiting, consuming certain medications that reduce the effectiveness of the pill; Even if you are doing everything right, there’s still a small chance you can get pregnant. So, can you get pregnant while on the pill? In this article, we will find out how effective birth control is, and in what situations it can fail to prevent pregnancy. In addition, we will tell you how to ensure a safe sex life and some early signs of pregnancy.

Effectiveness of the birth control pill

Each type of pill has a unique level of effectiveness, therefore there are different factors that cause failure in preventing pregnancy.

Hormonal methods

These methods release progestin (a form of progesterone) or a mixture of progestin and synthetic estrogen. They will stop ovulation ( – everything you need to know about ovulation); thin the layer covering the uterus and make it difficult for the embryo to implant; preventing sperms to enter the uterus by thickening the cervical mucus.

How do Hormonal methods fail in preventing pregnancy?

If you forgot to take the pills regularly or got injections at the wrong time, Hormonal methods would fail in preventing pregnancy. Moreover, antibiotics can also neutralize the effect, keep that in mind.

Birth control with Intrauterine devices (IUD)

This is a T-shape device that is inserted into the uterus. There are 2 types of IUDs, including Hormonal IUDs and copper IUDs (find more about copper IUDs from here.

The copper IUDs will change the path of sperm when they try to enter the uterus. On the other hand, hormone IUDs will emit hormones, which prevent pregnancy. Research from the Association of Reproductive Health Professionals (ARHP) shows that the success rate of Hormonal IUDs is 99% for 3-5 years post-injection. And the success rate of copper IUDs is 99% for 12 years post-injection.

However, Hormonal IUDs need a week after injection to adapt and start producing hormones. Therefore, these methods will fail if you have unprotected sex during that week. Both IUDs can also fall out of the cervix, which will make pregnancy possible.
