2 period in a month

Christine

Is it normal of having 2periods in a month ? My first period was aug29 and my last was sept3. And when sept18 after my xray of that day im have spotting until now. But sometimes its not just spot. Its more like a normal period.

Pls guys answer im stress about this :( im scared if this is normal or is it because of xray,

And btw in pregnant women is it normal to have bleeding b4 you knows that you might be preggy ?
