- Light spotting or bleeding is very common in early pregnancy and often doesn't mean there is a problem.
- Harmless causes include implantation bleeding or changes to the cervix.
- Heavy bleeding, severe one-sided pain, or feeling faint are warning signs that require urgent medical attention.
- Contact your local NHS Early Pregnancy Unit (EPU) or GP for advice if you are concerned.
Is Bleeding in Early Pregnancy Always a Bad Sign?
Firstly, try not to panic. Spotting or light bleeding happens in roughly one in four pregnancies, and many of these women go on to have perfectly healthy babies. There are several reasons you might bleed that are not a cause for alarm.
This can include 'implantation bleeding', which happens when the embryo burrows into the womb lining. Your cervix also softens and has an increased blood supply during pregnancy, so it can sometimes bleed a little after intercourse, for example. These causes are usually associated with very light, pinkish or brownish spotting.
When to Be Concerned: Key Warning Signs
The time to be concerned is when the bleeding is heavier, like a period, and is bright red. Passing clots or having crampy, period-like pain in your lower abdomen alongside the bleeding are also worrying signs.
The most urgent warning signs are severe, sharp, one-sided lower abdominal pain, feeling very dizzy or faint, or experiencing pain in the tip of your shoulder. These can be symptoms of an ectopic pregnancy, where the pregnancy implants outside the womb, which needs immediate medical attention.
What to Do and What to Expect at the Hospital
For any bleeding that worries you, you should seek medical advice. You can call your GP or your local NHS Early Pregnancy Unit (EPU) for guidance. If you have any of the urgent warning signs mentioned above, you should go straight to A&E.
When you are assessed, we will ask about your symptoms and may need to perform an examination. Usually, an ultrasound scan is the best way to find out what is happening. The scan can check if the pregnancy is in the right place and whether we can see a heartbeat.
Frequently asked questions
What does an implantation bleed look like?
An implantation bleed is light bleeding or spotting that happens when the fertilised egg attaches to the lining of your womb. It typically occurs around the time your period would have been due, is very light (pink or brown), and lasts for a day or two at most.
Should I go to A&E if I'm bleeding in early pregnancy?
You should go to A&E if you are bleeding very heavily, have severe abdominal pain (especially if it's one-sided), feel dizzy, have pain in your shoulder tip, or have collapsed. These can be signs of an ectopic pregnancy, which is a medical emergency.
Can stress cause bleeding in early pregnancy?
There's no medical evidence to suggest that emotional stress can cause bleeding or miscarriage. Early pregnancy bleeding is almost always caused by a physical process, whether that's harmless implantation or a developing problem with the pregnancy.
If I bleed, does it mean I'm having a miscarriage?
Not necessarily. Light bleeding or spotting is very common and many of these pregnancies continue without any issues. However, bleeding can be a sign of a miscarriage, which is why it's always important to get it checked by a healthcare professional.
