Great you are on the meds now. I don't know about the other tests, but the viral load, I think, is reporting the same thing in 2 ways. Under 15 at 3 weeks looks good to me- it means there is a scrap of something left but almost all gone. The test can't count any lower. Usually, people test after 28 days. You will get more expert answers, but to reassure you, it is working well. For instance, I was showing about 25 at 4 weeks, didn't become undetected until 18 week mark. Slay on!
