First row in DataGrid missing - vb.net

Question

I'm trying to output a data grid that retrieves user data and puts it in a table. When I try to do this, I believe the first row is replaced by the column name, then an additional empty row gets added to the bottom. Can anyone see any discrepancies with this code chunk that may cause it to do this?
Data Input:
Output Given:
Here's my code:
Dim mRow As Integer = 0
Dim newpage As Boolean = True
With DataGridViewONE
Dim fmt As StringFormat = New StringFormat(StringFormatFlags.LineLimit)
fmt.LineAlignment = StringAlignment.Center
fmt.Trimming = StringTrimming.EllipsisCharacter
Dim y As Single = 770 'e.MarginBounds.Top
Do While mRow < .RowCount
Dim row As DataGridViewRow = .Rows(mRow)
Dim x As Single = e.MarginBounds.Left
Dim h As Single = 1
For Each cell As DataGridViewCell In row.Cells
Dim rc As RectangleF = New RectangleF(x, y, cell.Size.Width, cell.Size.Height)
e.Graphics.DrawRectangle(Pens.Black, rc.Left, rc.Top, rc.Width, rc.Height)
If mRow = 0 Then
e.Graphics.DrawString(DataGridViewONE.Columns(cell.ColumnIndex).HeaderText,
.Font, Brushes.Black, rc, fmt)
Else
e.Graphics.DrawString(DataGridViewONE.Rows(cell.RowIndex).
Cells(cell.ColumnIndex).FormattedValue.ToString(),
.Font, Brushes.Black, rc, fmt)
End If
x += rc.Width
h = Math.Max(h, rc.Height)
Next
newpage = False
y += h
mRow += 1
If y + h > e.MarginBounds.Bottom Then
e.HasMorePages = True
mRow -= 1
newpage = True
Exit Sub
End If
Loop
mRow = 0
End With
EDIT
I have found that the ColumnIndex replaces the first row. Technically, if mRow was set to -1, there wouldn't be an issue, but doing so gives the error that index cannot be a negative value.
If mRow = 0 Then
e.Graphics.DrawString(DataGridViewONE.Columns(cell.ColumnIndex).HeaderText,
.Font, Brushes.Black, rc, fmt)
Replacing it with the Row DrawString would give the output I need but without the column headings
