###Human: What does very little vaginal bleeding mean? ###Assistant: Hi. I am pretty sure this will be the beginning of periods. These little bit variations in days and amount of bleeding are common. Ultimately, in a day or two, you will have your normal bleeding periods. Another possibility is lost pregnancy. Sometimes, conception occurs and just get lost before even next menstural day, and misunderstood as normal periods. So just watch for abnormally prolonged bleeding like for more than seven days. But I believe that it would be normal periods.
