Side Effects of Birth Control Pills: 10 Effects You Should Expect

According to the Family Magazine service at SaedNews, taking birth control pills is a hormonal method of preventing pregnancy. These pills can cause side effects that manifest differently in different individuals. Birth control pills prevent the body from producing eggs, meaning there is no egg available for fertilization by sperm, and pregnancy is not possible. To choose the right option, it is important to consult a gynecologist and be aware of the potential side effects.

This article explains the various side effects of birth control pills. Before using them, you should know how different types of pills can affect your body. Reading this article will take about 5 minutes.


1. Spotting Between Periods

Sometimes, birth control pills can cause spotting, which is light bleeding between menstrual periods. These spots are usually brown. Spotting is one of the most common side effects of LD pills and other types of birth control pills. It occurs as the body adjusts hormone levels and the uterus attempts to thin its lining.

For first-time LD pill users, the pills are usually taken once daily at a specific time, depending on the type. Follow the instructions on the leaflet or consult a pharmacist or gynecologist. Proper use reduces the likelihood of spotting.

If your natural menstrual cycle is disrupted by the pill, discuss cycle adjustments with your doctor.


2. Nausea

Some people may experience mild nausea after taking birth control pills, which usually fades over time. Taking pills with food or before sleep can reduce nausea. Severe or persistent nausea is not normal and requires medical attention. This can also occur with Cyble pills.


3. Breast Tenderness

Breast sensitivity is a common early side effect. Wearing a supportive bra can help. Hormones in the pills may also cause slight breast enlargement. If pain or lumps occur, consult a doctor. Roquin pills are known to cause breast tenderness.


4. Headaches and Migraines

Hormonal pills can trigger headaches and migraines, sometimes increasing their frequency. Changes in estrogen and progesterone levels can contribute. LD pills generally do not cause headaches, but emergency levonorgestrel pills may. For those with PMS-related migraines, some birth control pills may relieve pain.


5. Weight Changes

Research has not definitively linked birth control pills to weight gain, though some fluid retention and minor changes in fat or muscle mass may occur. Some users may experience weight loss instead. Ovuset LD pills may cause weight changes.


6. Mood Changes

Hormones significantly affect mood. Pills like Dezolest can cause emotional changes. Switching types under gynecologist guidance may resolve these effects. Marolin pills are also known to cause mood fluctuations.


7. Menstrual Delays

Birth control pills can sometimes stop periods temporarily. Factors like stress, illness, travel, hormonal imbalances, or thyroid disorders may contribute. Monitoring and consulting a doctor is important. Pills for PMS symptom management should be taken under medical supervision.


8. Changes in Libido

Hormonal changes may decrease sexual desire. In some cases, confidence in preventing pregnancy can increase libido.


9. Vaginal Discharge Changes

Pills may alter vaginal secretions. If dryness occurs, use lubricants during sex. Discharge changes are normal, but unusual color or odor may indicate infection.


10. Eye Changes

Some studies show that birth control pills may thicken the cornea, affecting contact lens use. Discuss with your doctor if this occurs.


How Side Effects Manifest

Women often worry about side effects of oral contraceptives (OCPs), including reduced libido, nausea, spotting, and increased body hair. Side effects vary depending on the type of pill: combined (estrogen and progesterone), monophasic, multiphasic, extended-cycle, progesterone-only, LD, and emergency contraceptives. Effects usually subside after 2–3 months but may persist.

Breastfeeding users should be aware that emergency pills may affect milk volume. Always consult a doctor before use.

Long-Term Risks

Combined LD pills may increase the risk of cardiovascular events like stroke, heart attack, or blood clots. Individuals with untreated hypertension or a family history of heart disease should consult a specialist. Hormonal fluctuations may also slightly raise the risk of cancers such as breast, ovarian, cervical, and colorectal cancer.
