Understanding and identifying implantation bleeding

April 12, 2018

You’re trying for a baby and now it’s a waiting game. A waiting game that probably means you’re keenly looking out for any early hints you’re pregnant. Then you spot signs your period might be on its way. Before getting upset consider whether it could be implantation bleeding instead.

What is implantation bleeding?

Implantation bleeding happens when a fertilised egg attaches itself to the lining of the uterus in order to begin growing. It is completely normal and does not need any medical treatment. It’s thought about a third of women experience implantation bleeding. The difficulty is that it happens at a similar time in your cycle to menstruation, so it’s often confused with having an early period.

What are the signs?

  • A pink or brownish discharge or spotting
  • Light or faint cramping
  • Mood Swings
  • Headaches

The tricky thing is that most of these symptoms can also be early signs you are pregnant.

Implantation bleeding or period?

There are several key differences between implantation bleeding and menstruation which can help you work out whether you’ve conceived or not.

  • Duration: as implantation bleeding only happens while the egg is fixing itself to the uterus, it may last as little as a few hours or up to 1-2 days. It will remain light and possibly stop and start during this time. There are normally no clots. If bleeding starts off light, but gets heavier, has a constant flow and lasts 4-7 days it is almost certainly your period.
  • Colour: for implantation bleeding the discharge or spotting will usually be pinkish or dark brown, whereas period blood tends to be bright, vibrant red.
  • Timing: implantation bleeding usually happens about 10 days after ovulation, while menstruation normally occurs after 14. So pinkish spotting on day 22-25 is more likely to be implantation bleeding than first signs of menstruation (usually around day 26-27).
  • Cramping: it is possible to experience light cramping when the egg is attaching itself to the womb, but it would be very faint and not increase in strength.

Are there any times when I should be worried by implantation bleeding?

This very early sign of pregnancy is not usually a reason to be concerned; it is perfectly normal and no risk to the developing baby. However, if you are also experiencing lower abdominal pain, nausea, dizziness or vomiting you should see your doctor as is may be an indication of an ectopic pregnancy.

Still not sure?

As with a lot of early signs of pregnancy, the only real proof that you’re on the path to parenthood is a pregnancy test.  If you think you’ve experienced implantation bleeding, the advice is that you need to wait at least 3 days before taking a home test.  Before that, it’s unlikely that enough of the pregnancy hormone hCG to give a positive result.  If you can bear to wait 5 days, there’s even more chance it will be accurate. In the meantime keep looking out for other early signs.
