I think alternate day testing with SMU will give you the best progression with lowest margin of error.
By SMU I mean second morning urine. Get up, pee, don't drink anything pee again then test. I can usually squeeze something out within half an hour. That way any dilute urine in your bladder from early on in the evening is gone and you haven't started diluting down that days urine.
Alternate day testing is better than daily testing to show progression as it takes 48 hours for hCG to double and about generally it seems tests get noticeably darker at the same rate. If you do test every day then compare tests as if you were testing alternate days. EG compare 14dpo to 12dpo not 13dpo.
Its all very well telling people not to test, but some of us find it a great comfort and very interesting to do so. Best to know what your looking for and when to worry if you want to test regularly. Yes people might "worry" and come on here asking for questions but those people may worry equally as much if they can't test and see what's going on with their body.
