You need to self ground for a few weeks anyway until the doc gets the HbA1c. 10 and you SHOULD be grounded. If you ask for the doc's letter, he'll not lie- he'll say the HbA1c was 10.
One of the rare times I'll actually GIVE advice (not just how to work certification): You shouldn't be flying like that anyway. There is a 90 day stabilization period for diabetes, because you don't really know that "diet and resulting weight loss seems to be controlling it". You only know that it likely will have a great impact, and when you get a Hb A1c of 8 or hopefully 7 you'll know and be able to show it did.
By letter of the law you can get a cert now as you don't have the meds. But my advice to you would be do NOT attempt to fly, so you might as well sit out the days until the HbA1c. The longer you wait, the lower it will be (it's the last 90 day' moving average of your control, and as you get lower, it too will go down). At a 135 average level, you vision will not be quite right. You shot a "10" because your overnight glucose is completley out of control, an is your one hour postprandial (after eating) glucose.
At 150 average you'll be on insulin. You DON'T want to go THERE.
So don't go to the AME until you have the new HbA1c in hand. It'll be a few months, but you will live MUCH LONGER and have a lesser risk of Heart Attack and stroke for doing it right, as well as much less of a chance of your vision blurring out in flight.....if you don't fly for a while.
IF you don't get a decent HbA1c in 90 days, a marginally obtained medical would be of no use anyway, as Diabetes is on the part 67 list of grounding conditions and you would be grounded anyway (so for this one you can't self certify between medicals).
In short, you can get a medical based on not taking the meds. But right now it's marginal and not safe. My advice: stay down, get it under control, show that it is under control, save the $80 for the medical until you can get it right.
