Bleeding or pain in early pregnancy is frightening, and it has several possible causes. Two of the most important are ectopic pregnancy, where the pregnancy grows outside the womb, most often in a fallopian tube, and early miscarriage, the loss of a pregnancy before 12 weeks. An ectopic pregnancy can cause life-threatening internal bleeding, so knowing the warning signs matters. This guide explains the symptoms, how doctors tell these conditions apart, and what treatment involves.
Quick answer: Ectopic pregnancy affects about 1 to 2 in every 100 pregnancies. Typical signs are one-sided lower abdominal pain, vaginal spotting or bleeding, and a missed period, usually between 4 and 12 weeks. Shoulder-tip pain, fainting or severe pain can mean a rupture and is an emergency. Diagnosis uses a transvaginal ultrasound and blood hCG levels. Early miscarriage is more common, occurring in roughly 10 to 20 in 100 known pregnancies, and usually happens because of chromosome problems in the pregnancy, not because of anything the mother did.
Key takeaways
- ✅ Any pain or bleeding in early pregnancy should be checked, especially before a scan has confirmed the pregnancy is in the womb.
- ✅ A positive home pregnancy test does not show where the pregnancy is.
- ✅ Ectopic pregnancy cannot continue normally and always needs medical care.
- ✅ Most women who have a miscarriage or ectopic pregnancy go on to have healthy pregnancies later.
Call 108 or go to emergency immediately if you are, or might be, pregnant and have:
- Sudden, severe pain in the lower abdomen
- Pain in the tip of the shoulder
- Dizziness, fainting, a racing heartbeat, or pale, clammy skin
- Heavy bleeding, soaking a pad in an hour
What is an ectopic pregnancy?
Normally a fertilised egg travels down the fallopian tube and implants in the lining of the womb. In an ectopic pregnancy it implants elsewhere, in over 90% of cases in the fallopian tube. The tube cannot stretch to hold a growing pregnancy and may burst (rupture), causing heavy internal bleeding.
Risk factors:
- A previous ectopic pregnancy or surgery on the fallopian tubes
- Past pelvic infections such as chlamydia or gonorrhoea (pelvic inflammatory disease)
- Pregnancy with an IUD (copper-T) in place, or after tubal ligation
- Fertility treatment such as IVF
- Smoking and age over 35
About half of women with an ectopic pregnancy have no known risk factor.
Symptoms of ectopic pregnancy
- A missed period and a positive pregnancy test
- Pain on one side of the lower abdomen, which may be mild at first
- Vaginal spotting or bleeding, often darker and different from a normal period
- Pain when passing stools or urine, or diarrhoea
- Shoulder-tip pain, which can mean blood irritating the diaphragm
Signs of early miscarriage
- Vaginal bleeding, from light spotting to heavy bleeding with clots
- Cramping pain in the lower abdomen or back
- Passing tissue or fluid from the vagina
- Pregnancy symptoms such as nausea and breast tenderness suddenly fading
Light spotting is common in early pregnancy and often settles on its own, but it should still be checked.
| Type of miscarriage | What it means |
|---|
| Threatened | Bleeding, but the cervix is closed and the pregnancy is still developing. Many continue normally. |
| Inevitable | Bleeding with the cervix opening; the pregnancy cannot continue. |
| Incomplete | Some pregnancy tissue has passed but some remains in the womb. |
| Complete | All pregnancy tissue has passed and the womb is empty. |
| Missed (silent) | The pregnancy has stopped developing but has not been passed, often found on a routine scan. |
How doctors tell them apart
- Transvaginal ultrasound: the main test. It shows whether the pregnancy is inside the womb and whether it is developing, or finds a mass or fluid outside the womb.
- Blood beta-hCG: the pregnancy hormone. In a healthy early pregnancy it usually rises by at least about half over 48 hours; a slow rise, plateau or fall can point to ectopic pregnancy or miscarriage. When hCG is above the level at which a pregnancy should be visible (roughly 1,500 to 3,500 IU/L) but the womb is empty, ectopic pregnancy is suspected.
- Blood count and blood group: to check for blood loss and whether anti-D is needed for Rh-negative mothers.
Sometimes the location cannot be seen at first ("pregnancy of unknown location"), and repeat hCG tests and scans over a few days are needed.
Treatment
Ectopic pregnancy:
- Watchful waiting for a small, stable ectopic with low and falling hCG, with close follow-up.
- Methotrexate injection, which stops the pregnancy growing, when the woman is stable, the ectopic is small and hCG is not too high. Regular hCG checks follow until it reaches zero, and pregnancy should be avoided for at least 3 months afterwards.
- Surgery, usually keyhole (laparoscopy), to remove the pregnancy and often the affected tube, and always if there is rupture or heavy bleeding.
Miscarriage: many complete naturally at home (expectant management). Others are helped with medicines (misoprostol, sometimes with mifepristone) or a minor procedure to empty the womb. Rh-negative women may need an anti-D injection. See a doctor again for heavy bleeding, fever or foul-smelling discharge, which can mean retained tissue or infection.
After a pregnancy loss
Grief after miscarriage or ectopic pregnancy is real, whatever the stage. Talk to your partner, family or a counsellor if you are struggling. Most early losses are one-off events. Tests for an underlying cause are usually offered after two or three losses in a row. After an ectopic pregnancy, an early scan at about 6 weeks in the next pregnancy is recommended to confirm its location.
Frequently asked questions
Can an ectopic pregnancy be moved into the womb?
No. There is no way to transfer an ectopic pregnancy into the womb, and it cannot survive outside it.
Did I cause my miscarriage?
Almost certainly not. Most early miscarriages are due to chromosome problems. Normal work, exercise, sex and travel do not cause miscarriage.
Will a urine pregnancy test stay positive after a miscarriage?
It can stay positive for a few weeks while hCG falls. If it is still positive after about 3 weeks, see your doctor.
