Could it be that I might be pregnant because last month February I did not experience two periods in one month.

Is it normal to have a three day period one week , then the next week a two day period I've never experienced this before.

Is this normal to go through this?

It may just be a slightly off cycle, which can happen. How long is your normal period? If you are concerned about possible pregnancy, try a test.
