Implantation Bleeding

When trying to get pregnant, it may be devastating to notice bleeding on about the same day as next expected menstruation. However, bleeding might not at all be a regular period, but something that we call implantation bleeding – an early sign of pregnancy.


About  Implantation Bleeding

Implantation bleeding usually starts about 10  days after egg is fertilized with sperm. Commonly, this happens just several days before woman expects her period. When the fertilized egg attaches itself in the uterus, it may disrupt tiny vessels. The disruption can cause bleeding, resulting in what we call implantation bleeding. The process itself is not abnormal, vice versa, about every third pregnant female experiences it.

It is not easy to tell a difference between menstruation and implantation bleeding. Discharge or spotting  during implantation bleeding may be pink, red or brownish, accompanied with light cramping, headaches  and mood swings. Not that much of a difference. In some cases, intuition may help because implantation bleeding might still look and feel different. For example :


  • Implantation bleeding is usually of a lighter or simply a different color and makes the two cases distinguishable.
  • If a woman experiences clotting during period, it will not be the case during implantation bleeding.
  • Implantation bleeding will usually stop sooner than regular periods, especially for females who experience longer ones. The duration may last  from several hours up to two days.
  • And yes, sometimes it is impossible to tell a difference.


Implantation bleeding will terminate on it’s own and doesn’t need any kind of medical intervention.  After the bleeding starts, it is the best practice to wait several days before doing the pregnancy test.


Are there complications?

Light bleeding is completely normal and sometimes may be just a little bit heavier because of a simple irritation after sexual intercourse or pelvic exam. Several infections may also contribute to bleeding, but it is still normal and will stop on its own.

However, if tests confirm that a female is pregnant and the bleeding is present, it is recommended to contact a doctor immediately (especially if bleeding has become heavy). Heavy bleeding early in pregnancy might indicate following issues :


  • Ectopic pregnancy – a condition when an embryo implants outside the uterus instead of the inside.
  • Molar pregnancy – genetic problem / error that occurs during fertilization, causing growth in the uterus but not the actual pregnancy.
  • Miscarriage
