FAQ: Short Period: Am I Pregnant?

Q: My period only lasted 2 or 3 days. Could I be pregnant?

Vaginal bleeding lasting three days or less can occur for various reasons and rarely indicates pregnancy. A short period is often a reaction to external factors such as stress or medication.
As a rule, menstrual bleeding usually lasts 3-7 days.

In early pregnancy, hormonal changes may cause short, light vaginal bleeding (spotting). 
Also, a short period of bleeding, known as implantation bleeding, may occur at implantation (when a fertilized egg implants in the uterus). However, these are not the same as menstrual bleeding. Implantation bleeding occurs earlier in the menstrual cycle, around six days after conception, which is before one’s period is due. It also differs in color by being a lighter shade of red or brown.

Perhaps you already knew about these possible causes of spotting, and now you feel unsure because of a short period.
It may be reassuring to know that the absence of one’s period is the most notable sign of early pregnancy. A short period is not necessarily a sign of pregnancy. It may simply be a "normal" period that is slightly shorter than usual.
