Is this a good line progression?

Just wanted opinions. I ran out of cheapies & doc doesn't wanna see me til Nov 11th. I started this 2 days before AF was due and was gonna grab some more digitals to test each week until my Appt but I doubt Ill be able to wait, so its better to just have no tests in the house or I'll go broke. Any opinions? Should I just order more cheapies? Lol
