Some women get pregnant very quickly, in fact 1 in 3 women who are having regular sex (every 2 to 3 days) or timing sex around ovulation, will conceive within a month.
If they are having regular unprotected sex:
- more than 8 out of 10 couples where the woman is aged under 40 will be pregnant by 1 year
- more than 9 out of 10 couples will get pregnant by 2 years.
Regular unprotected sex means having vaginal sex every 2 to 3 days without using contraception.
However, age makes a difference. Starting at age 34 your ability to get pregnant starts to decline gradually.
Age and getting pregnant
Your age is not something you can control. Many women are having babies later in life for very valid reasons such as not feeling stable enough to support a child (for example, with money or housing), not wanting to have a child before or not having a partner to have a child with.
However, we know that fertility (ability to get pregnant) declines with age and this decline speeds up after the age of 35. This is because the number and quality of eggs decreases. Male fertility also declines with age, though not as much as female fertility.
One study found that for couples having regular unprotected sex:
- around 7 out of 10 women aged 30 will conceive within one year
- around 6 out of 10 women aged 35 will conceive within one year
- around 4 out of 10 women aged 40 will conceive within one year.
After the age of 40, it gets harder to conceive and you may be offered fertility treatment.

Improving your fertility
Fertility is affected by lifestyle. There are some things you can do to improve your fertility. For example, if you smoke it will take you longer to get pregnant than a non-smoker. If you give up smoking now, your chances of conceiving faster will increase.
Other things you can do to improve your fertility include:
- being a healthy weight
- being active
- eating a healthy, balanced diet
- cutting caffeine to under 200mg a day
- avoiding alcohol
- avoiding recreational/illicit drugs.

Stopping contraception and getting pregnant
Some types of contraception may delay fertility for a while after you stop taking it. For example the progestogen-only injection for contraception may delay normal fertility for up to one year after the last injection. Find out more about stopping contraception.
If you take the contraceptive pill many doctors advise that you should delay trying to conceive until you have had one normal period. This helps them to date a pregnancy more accurately.
When should I get help with conception?
Around 1 in 7 couples have difficulty conceiving. This is approximately 3.5 million people in the UK.
Speak to your GP if you have been trying for a year conceive.
Many doctors prefer you to have been having regular sex without contraception for at least a year before referring you for fertility tests. Regular sex means 2-3 times a week.
You should see your GP sooner if:
- you are over 36
- you have a known fertility issue, such as endometriosis or polycystic ovary syndrome (PCOS)
- your partner has a known fertility issue, such as low sperm count
- you are concerned you or your reproductive partner may have an undiagnosed medical issue that may be affecting your ability to get pregnant.
