The Plan B pill does have the side effect of causing a period to be a week early or a week late, as well as "breakthrough bleeding" (bleeding in-between periods).
It is impossible to say if the bleeding you experienced was definitely an early menstrual period or breakthrough bleeding from Plan B, as I assume your period began around February 20th, and that would have been a very short cycle for another period to begin on March 7th...but either way (since you did experience a week of bleeding), Plan B did slightly alter your cycle for that month. It does not matter if this was never experienced before...it is a new cycle with a new medication (for that cycle), and is a normal side effect of this pill.
You can take a home pregnancy test to rule out pregnancy, or wait until you have another menstrual period. There are no definitive answers, unfortunately.
For a more reliable form of birth control (and, one you don't have to worry about knowing if your period began or not), please consider using the pill or other hormonal contraceptive, since you have taken Plan B multiple times. The pill is 99% effective at preventing pregnancy, whereas Plan B is about 70-80% effective at preventing pregnancy...that could be a BIG difference when you are not wanting to be pregnant, or worry that you might be, right?!
