Part 1
Birth control has been a game-changer for women’s health and autonomy, but how much do we really know about what we’re putting into our bodies? If you’ve ever wondered about hormonal birth control—how it works, its benefits, and the risks—you’re in the right place. Let’s break it all down in a way that’s easy to understand (because let’s be real, medical jargon can be a lot).
How Does Hormonal Birth Control Work?
Hormonal birth control prevents pregnancy by altering the body’s natural hormone levels to stop ovulation (aka, no egg = no pregnancy). It also thickens cervical mucus, making it harder for sperm to get through, and in some cases, it thins the uterine lining so that implantation is less likely.
There are two main types of hormonal birth control:
Combination Birth Control (Estrogen + Progestin) – Includes the pill, patch, and ring.
Progestin-Only Birth Control – Includes the mini-pill, implant, shot, and hormonal IUDs. This option is ideal for those who cannot tolerate estrogen, such as breastfeeding mothers or women with a history of blood clots.
How Exactly Does It Stop Pregnancy?
Progesterone (or synthetic progestin) is the key player in preventing pregnancy, and it does this in three ways:
Stops Ovulation – Normally, the follicle-stimulating hormone (FSH) and luteinizing hormone (LH) help an egg mature and release it from the ovary. Birth control suppresses these hormones, preventing an egg from being released in the first place.
Thickens Cervical Mucus – This makes it more difficult for sperm to travel through the cervix and reach an egg.
Thins the Uterine Lining – If an egg does get fertilized, the lining of the uterus is not thick enough for implantation, making pregnancy less likely.
The Pros: Why Some Women Love It
Hormonal birth control is widely used for good reason:
Highly effective – When taken correctly, the pill is over 99% effective.
Regulates cycles – Many women experience more predictable and lighter periods.
Helps with hormonal acne – Some birth control pills reduce breakouts.
Can reduce period pain – Hormonal methods may help with cramps and heavy bleeding.
Manages conditions like PCOS & endometriosis – Many doctors prescribe birth control to help with these conditions.
The Risks: What You Should Consider
Like any medication, hormonal birth control comes with potential downsides. These aren’t meant to scare you—just things to be aware of so you can make an informed choice.
Increased blood clot risk – Especially with the pill, patch, or ring, there’s a higher risk of blood clots, particularly for smokers or women over 35. (Source)
Potential mood changes – Some women report mood swings or increased anxiety. (Source)
Slightly higher breast cancer risk – Studies suggest a small increase in risk while using hormonal contraception. (Source)
Can affect libido – Some people notice a decrease in sex drive while on birth control.
Not for everyone – If you have a history of migraines with aura, high blood pressure, or clotting disorders, some types of birth control may not be safe for you.
What Are Your Other Options?
If hormonal birth control isn’t the right fit, don’t worry—there are non-hormonal alternatives like:
The Copper IUD – Effective for up to 10 years without hormones.
Fertility Awareness Methods – Tracking ovulation and cycle patterns.
Barrier Methods – Condoms, diaphragms, and cervical caps.
Final Thoughts
Hormonal birth control works by completely altering the way your body prepares for pregnancy. Because it changes hormone levels, it can have widespread effects on the body beyond just contraception.
It’s important to educate yourself on all available options and talk to a healthcare provider to make the best choice for your body.
