Bleeding during pregnancy

Bleeding during pregnancy: What you need to know

Any vaginal bleeding during pregnancy is a reason to seek immediate medical attention. This is one of the most important rules every expectant mother should know. Although the causes can vary, and it does not always mean the worst, only a medical professional can determine the source of the problem and provide the necessary help.

Possible causes at different stages

The causes of bleeding depend heavily on the gestational age:

• First trimester: Light spotting may be implantation bleeding when the fertilized egg attaches to the uterine wall. It can also be caused by increased cervical sensitivity. However, bleeding can also be a sign of serious conditions such as threatened miscarriage or ectopic pregnancy.
• Second and third trimesters: In this period bleeding may signal placental problems (placental previa or abruption) or the onset of preterm labor.
