As a sexually active woman, you can run into the risk of unwanted pregnancies if you do not use contraception when engaging in sex with your partner. Statistics have shown that 84% of couples who have regular sex without contraception will get pregnant within a year. Another 92% will get pregnant within two years.
As a rule of thumb, if you are a woman who wants to have only two children, you may need to prevent pregnancy for 28 years or 236 menstrual cycles. A number of factors, including age and frequency of sex, plays a part in determining how easily you can become pregnant.
Apart from preventing pregnancy, other women like you may also choose to use contraception because of certain health conditions. For instance, some hormonal birth control methods may help to regulate your period, reduce acne or lower endometriosis-related pain.
Other Reasons for Using Birth Control Methods
Here are other common reasons for using contraception:
- You love children but you may have decided that you do not want to have children yet or perhaps are still relishing the joys of couplehood with your partner
- You may not have a stable partner to help in parenting a child
- For financial reasons, you may not be able to take on the extra financial responsibilities that comes with having a baby
- You may feel that your family is complete, so you want to make sure that you do not become pregnant again
- You want to focus on caring for the children you already have
- It may not be safe for you to be pregnant for health-related reasons
Types of Birth Control Methods in Singapore
One of the most common and cost-effective ways of preventing pregnancy is to use a condom, which can be easily purchased at the pharmacy, supermarket or convenience store. Condoms reduce the odds of getting or passing on STDs but are only about 85% effective in preventing pregnancies.
Other contraceptive options that promise a higher success rate of preventing pregnancies include the following:
1. Birth Control Pills
Also known as contraceptive pills, birth control pills contain hormones (estrogen and progestin) that stop ovulation so there are no eggs for the sperm to fertilise. They also thicken the mucus in the cervix, making it harder for sperm to move. The pills also thin the lining of the uterus, making it difficult to implant a fertilised egg.
Pros & Cons of Birth Control Pills
When used correctly, birth control pills are highly effective – up to 91% in preventing pregnancies. It is also easy for you to reverse your fertility cycle simply by stopping the pill.
If you have menstrual-related issues, the pill can also help to make your menstrual flow less heavy and more regular. It can also improve premenstrual syndrome (PMS) symptoms.
The downside is that you have to remember to take the pill every day. It can be easy for things to get messed up if you forget to take your pill on a particular day. Medication or alcohol may also interfere with the pill’s effectiveness.
The side effects of birth control pills can vary a lot. One of the good side effects is that it may help to control acne. This is one reason why even sexually inactive people sometimes take them. Birth control pills are suitable for you if you are 50 years old and below, do not smoke and are in good health.
Side Effects of Birth Control Pills
Side effects of taking birth control pills may include:
- Sore or swollen breasts
- Small amounts of blood or spotting, between periods
- Lighter periods
- Mood changes
- Mild headache
These side effects are usually manageable and should not be a cause of concern. If you are experiencing more than just mild discomfort, you should always consult a doctor.
Other side effects are less common, but are more serious and may indicate an underlying condition. These side effects can be easily remembered using the acronym ‘ACHES’, and include:
- Abdominal pain
- Chest pain
- Eye problems
- Swelling or aching in your legs or thighs
If you experience these symptoms, consult a doctor immediately or go to the emergency room as it may indicate a more severe health problem such as liver or gallbladder problems, stroke, blood clots, high blood pressure, or heart diseases.
Cost of Birth Control Pills
Birth control pills range from $25 to $40 for a month’s supply depending on the brand you choose.

An EVRA® patch is a good option for those who find popping the pill a hassle as you only need to replace the patch weekly. During each monthly cycle, you wear it for three weeks and do not wear it during the 4th week. It also has less gastric side effects than the pill.
The disadvantage is that the patch is not transparent and you may feel a little uncomfortable wearing it due to the hot and humid weather in Singapore.

Pros and Cons of Birth Control Injections
Birth control injections are 94% to 99% effective as long as you remember to go for your jab. It is also a non-invasive method of birth control, which is preferred by some women.
One disadvantage of birth control injections is that it takes a long time to regain fertility – usually six to 12 months – should you decide to have kids in the future.

Pros and Cons of Contraceptive Implants
It has an effective rate of up to 99 per cent. It is a long-term contraceptive option as it lasts for three years . You will also regain your fertility quickly after you stop using it.

Pros and Cons of an IUD
It is up to 98% effective and can be left in the womb for up to five years. It is also a good choice for breastfeeding mums. You will also regain fertility once you remove it.
However, one main disadvantage is that it may cause irregular bleeding or spotting. This is why doctors do not usually recommend this as a first choice if you are anaemic or have heavy periods.
Complications are rare but there is a small risk that the IUD could fall out and cause an infection during the insertion. Other risks include difficulty in removing the device.
Side Effects of an IUD

7. Emergency Contraception (Morning-after Pill)
The morning-after pill is a contraceptive taken after sex. It works the same way as the birth control pill and can be used up to 120 hours after unprotected sex.
It is important to note that emergency contraception is not meant to be a birth control method. It serves to provide you with an alternative if you have not been using regular methods properly. For example, if you discovered a tear in the condom or forgot to take a birth control pill, you can use emergency contraception as a last resort. However, this pill may not work if you have already begun ovulation.
Side Effects of Morning-after Pills
The side effects of morning-after pills typically last only a few days and may include:
- Nausea or vomiting
- Breast tenderness
- Bleeding between periods or heavier menstrual bleeding
- Lower abdominal pain or cramps
Cost of Morning-after Pills
Each morning-after pill can cost between $40 to $50, which is quite expensive compared to the other birth control methods.
What is the best form of birth control for me?
In choosing the right form of birth control for yourself, factors such as your age, frequency of sexual activity, family history regarding certain illnesses, comfort level when using a particular method as well as your desire to be pregnant in the future are some of the key things you should consider.
It is recommended that you talk to your doctor to find out which method works best for you. Do not feel embarrassed if you have to clarify with your doctor how each method works. Having the right information is key and you should have sufficient information to make a decision on which birth control method you feel most comfortable with. When you have more knowledge on hand, you are better-placed to take control of your sexual health.
If you feel more comfortable discussing your options with a doctor in the privacy of your home, you can engage a house call doctor or consult a doctor through a video call. Should you need a repeat prescription of birth control pills or emergency contraception, you can simply consult a doctor online and have the pills delivered to your doorstep.
