A positive pregnancy test can bring joy, relief and worry all at once, especially after fertility treatment. This page explains simple steps for early pregnancy, the warning signs that need urgent care, and what is known about miscarriage. If you have had a loss, we hope it offers some comfort.
First steps in early pregnancy
Pregnancy is dated from the first day of your last period, not from the day you conceived. So by the time a period is missed, you are already counted as about 4 weeks pregnant.
| Week | What usually happens |
|---|---|
| 0 | First day of your last period |
| About 3.5 to 4 | A missed period, often one of the first signs; a home test can usually detect pregnancy |
| 8 to 12 | Booking appointment: health history, checks and screening information |
| 11 to 14 | Dating scan: checks the due date, development and number of babies |
The NHS says home pregnancy tests can tell you if you are pregnant from about 3 and a half weeks. If the result is unclear, test again a few days later or ask your doctor.
- Keep taking folic acidThe CDC advises 400 micrograms daily before and during early pregnancy to help prevent neural tube defects. Some people need a higher dose; ask your doctor.
- Book your first antenatal visitThe NHS recommends the first full antenatal (booking) appointment between 8 and 12 weeks. If you conceived with treatment, your fertility doctor may see you earlier.
- Have your dating scanA scan between 11 and 14 weeks checks how far along the pregnancy is and how the baby is developing.
- Know the warning signsLearn which symptoms need urgent care, listed below, and keep your clinic's contact details close.
- Take folic acid every day
- Tell your doctor about any medicines you take
- Rest when you need to and ask for help
- Smoke or drink alcohol
- Ignore heavy bleeding or severe pain
- Stop prescribed medicines without asking
Warning signs that need urgent care
Some light spotting can happen in early pregnancy and may have other causes. But some symptoms should never be ignored. Go to the nearest emergency department straight away if you are pregnant and have:
- Heavy bleeding that soaks a pad quickly
- Severe pain in your tummy
- Pain at the tip of your shoulder
- Feeling faint, dizzy or very unwell, or passing out
Ectopic pregnancy, where the pregnancy grows outside the womb, usually causes symptoms between weeks 4 and 12. Signs include pain low on one side, unusual bleeding, shoulder tip pain and pain when using the toilet. Sudden severe pain with dizziness is an emergency.
Understanding miscarriage
Miscarriage means losing a pregnancy early. According to Cleveland Clinic, about 1 in 10 known pregnancies end in miscarriage, and the risk falls as pregnancy goes on, to about 1 in 100 in the second trimester.
About half of miscarriages are caused by chromosome problems that happen by chance when the egg and sperm join. The risk also rises with the mother's age.
Other things can raise the risk, such as some long-term health conditions, smoking and drinking alcohol. But often, a miscarriage happens because there is a problem with the way the pregnancy develops, and it is not your fault.
There is no scientific proof that stress, exercise, sex or birth control pills cause miscarriage. Please try not to blame yourself.
Having one miscarriage can slightly raise the risk in a later pregnancy, but most women who have a miscarriage go on to have a healthy pregnancy.
If a miscarriage happens: care and recovery
The NHS describes miscarriage as losing a pregnancy before 24 weeks. The main sign is bleeding from the vagina, which can range from light spotting to heavy bleeding. Some people have no symptoms, and the loss is found on a scan.
- Cramping or pain in your lower tummy
- Passing tissue or fluid from your vagina
To check what is happening, a doctor will ask about your symptoms and may arrange blood or urine tests and a vaginal ultrasound scan.
| Option (before 14 weeks) | What it means |
|---|---|
| Waiting | Letting the pregnancy tissue pass naturally, with follow-up |
| Medicine | Tablets help the tissue pass |
| Procedure | The tissue is removed with gentle suction |
Your doctor will talk through which option suits you. Bleeding and tummy discomfort can last up to two weeks. The NHS advises waiting to have sex until your symptoms have gone. If your blood group is D-negative, you may be offered an anti-D injection.
Physical recovery often takes days to weeks, but there is no right timeline for your feelings. You can try for another pregnancy once your symptoms have settled and you feel ready.
Recurrent miscarriage: when to get checked
The NHS describes recurrent miscarriage as having 3 or more miscarriages. If this has happened to you, talk to a doctor. Tests may find a cause that can be treated, and you can also get support.
| Situation | Suggested next step |
|---|---|
| One miscarriage | Rest, recover and talk with your doctor about when to try again |
| 3 or more miscarriages | Ask for tests to look for a treatable cause |
| Any loss with ongoing distress | Ask for emotional support or counselling |
If you have had losses and are planning another pregnancy, our doctor can talk through your history and whether further tests would help.
Looking after your feelings
Losing a pregnancy can bring deep grief, even very early on. Emotional healing can take longer than physical healing. Partners grieve too, sometimes in different ways.
- Give yourself time to grieve
- Talk to people you trust
- Consider a support group
- Ask for help from a mental health professional if you need it
You do not have to cope alone. Counselling and support groups are available, and many people find it helps to talk with others who have been through a loss.
When to see a doctor
- Heavy bleeding, severe tummy pain, shoulder tip pain or fainting: go to emergency now
- Any bleeding or pain in early pregnancy, even if mild
- Pain low on one side, even before a positive test
- You have had 3 or more miscarriages
- You are struggling emotionally after a loss
