VBA Adding Wrong Dates

The code is supposed to project review dates 1 month, 2 months and 3 months after the start date, but the first "cell offset" line on is projecting the next day instead of next month, its driving me nuts!!, the others are working fine

Code:
Sub reviews()
Dim cell As Range

For Each cell In Range("L1:L200")
If IsDate(cell) Then
cell.Offset(, 10).Value = DateAdd("m", 1, cell.Value)
cell.Offset(, 11).Value = DateAdd("m", 2, cell.Value)
cell.Offset(, 12).Value = DateAdd("m", 3, cell.Value)
cell.Resize(, 10).AutoFill cell.Resize(, 11)
End If
Next cell
End Sub
