A light, short period can be an early indicator of pregnancy. However, if you are taking birth control pills, it is typically counted as a missed period if you have no bleeding at all. A light or very light period is still a period on the pills. Rarely, a very light period can be associated with a pregnancy if you missed more than one or two pills in a month.
If you suspect you may be pregnant, there are other signs to check for, including:
- swelling, tenderness, or tingling in the breasts
- the need to urinate more frequently
- fatigue
- nausea or vomiting
- abdominal cramping
- changes in appetite
- changes in digestion
- changes in mood
If you are pregnant, you will typically see more than one of these symptoms. A light period one month combined with several of these symptoms may indicate pregnancy. A light period one month with none of these symptoms probably does not.
