Understanding how hormonal contraception works can help you make informed decisions about your reproductive health. Birth control affects your natural hormone cycle in several ways, from suppressing ovulation to changing your bleeding patterns. Here's how hormonal contraception affects your body, and what to expect if you decide to stop.
How Does Your Natural Hormone Cycle Work?
Your menstrual cycle is orchestrated by four key hormones: oestrogen, progesterone, follicle-stimulating hormone (FSH), and luteinising hormone (LH).
Each month, rising oestrogen triggers ovulation, whilst progesterone prepares the uterine lining for potential pregnancy. When fertilisation doesn't occur, hormone levels drop and your period begins. According to research published in Frontiers in Neuroendocrinology, these hormonal fluctuations also influence brain connectivity and cognitive function throughout your cycle.
How Birth Control Changes Your Hormones
Hormonal contraceptives contain synthetic versions of oestrogen and progestin that alter your hormone cycle. A comprehensive review in PubMed confirms these mechanisms are consistent across pills, patches, rings, implants, and hormonal IUDs:
- Suppresses ovulation: Synthetic hormones prevent FSH and LH surges, stopping the release of eggs from the ovaries
- Thickens cervical mucus: Progestin creates a barrier that makes it difficult for sperm to reach the egg
- Thins the uterine lining: Reduced endometrial growth decreases the likelihood of implantation
- Stabilises hormone fluctuations: Consistent hormone delivery reduces the natural rise and fall of oestrogen and progesterone
Understanding Withdrawal Bleeds
The bleeding you experience during your placebo week isn't a true period. Called a withdrawal bleed, it occurs when synthetic hormone levels drop, mimicking the natural hormonal dip that triggers menstruation. Since ovulation hasn't occurred, your uterine lining is thinner, and the blood you shed differs from a natural period.
Many women find their withdrawal bleeds lighter and shorter. For relief from period discomfort, the Period SOS Cream provides natural support for cramps and bloating during your cycle.
Common Birth Control Hormone Effects
The contraception hormone impact varies between individuals. Common changes include:
- Lighter, shorter periods: Reduced endometrial growth means less tissue to shed
- Predictable cycles: Consistent hormone delivery creates regular timing
- Reduced cramps and PMS: Stabilised hormones ease monthly symptoms. The Super Rich Magnesium Body Lotion can provide additional muscle relaxation support.
- Breakthrough bleeding: Spotting is common during the first three months as your body adjusts
- Mood changes: Birth control, natural hormones interact with serotonin and dopamine. Some women feel more stable, whilst others experience anxiety or low mood.
- Symptom masking: Conditions like PCOS and endometriosis may improve on birth control, but symptoms often return after stopping
The American College of Obstetricians and Gynaecologists recommends discussing your complete health history with your provider to find the best approach for your needs.
What Happens When You Stop Birth Control
Stopping birth control allows your body's natural hormones to resume their natural rhythm. Most women regain hormonal balance within one to three months, though it can take up to nine months for cycles to fully regulate. Common experiences include:
- Irregular periods: Cycles may vary in length and flow as your body readjusts
- Acne returning: Hormonal fluctuations may trigger breakouts
- Mood fluctuations: Natural hormone shifts can affect emotional well-being
- Bloating and cramps: The Bloating SOS can help ease digestive discomfort during transition
- Post-pill amenorrhea: Some women don't get periods for several months. Consult your provider if your cycle hasn't resumed within six months.
Non-Hormonal Options
If you prefer to maintain your natural birth control hormone cycle, non-hormonal options exist. Copper IUDs provide effective contraception without altering hormones, though they may cause heavier periods initially.
Barrier methods like condoms have no hormonal impact. Fertility awareness methods (FAMs) can be up to 98% effective when practised correctly, allowing you to track your cycle's natural biomarkers.
Supporting Your Hormonal Wellness
Whether you're currently using hormonal contraception or transitioning off, supporting your body with hormone-safe products can help ease discomfort. For soothing comfort during cramps, the All-Natural Flaxseed and Lavender Pad offers heat or cold therapy for natural relief.

Frequently Asked Questions
1. Does birth control stop your natural hormones completely?
Hormonal birth control suppresses ovulation and reduces natural hormone fluctuations, but your body still produces some hormones. Synthetic hormones take over the regulatory role normally performed by your natural oestrogen and progesterone.
2. How long does it take for hormones to return to normal after stopping birth control?
Most women see their natural cycle return within one to three months. However, it can take up to nine months for hormones to fully regulate, particularly if you used long-acting methods.
3. Is the bleeding on birth control a real period?
No. The bleeding during your placebo week is a withdrawal bleed caused by the drop in synthetic hormones. Since ovulation hasn't occurred, it differs from a natural menstrual period.
4. Can birth control affect my mood?
Yes. Hormonal contraception can influence neurotransmitters that regulate mood. Some women feel more stable, whilst others experience anxiety or low mood. Discuss alternatives with your provider if you notice significant changes.
5. Will birth control affect my fertility long-term?
No. Hormonal contraception does not damage fertility. Your reproductive system resumes normal function after stopping, though it may take a few months for ovulation to return.
