The doctor (I assume he was a doctor and not just a nurse or something) said, when I asked him if 3 months was definitive, he said I'd need to come back at six months and nine months, ect. Three months IS definitive, isn't it? I asked the other doctor who seems to be in charge as I was checking out if three months would give sure results and he said yes, three months is plenty of time. He's the one I should trust, right? I know from reading on here, three months is apparently definitive. I don't need to go back and retest, do I?
