Can a six week neg change?

I posted a few days ago about continuing symptoms and just wanted to throw another question out there.  I tested negative at four weeks with the duo test and again with antibody test at six weeks.  Has anyone heard of such results changing to positive? I am now at nine and a half weeks and despite sound advice am suffering the same worries I have read throughout the forum.

don't listen to mitm. joecool21 is right test a 12/13 weeks.

All are saying the same, get a final test at 12/13 weeks. The probability for a DUO test at 4,6 weeks turning positive are remote, if your exposure was typical very very remote.

I can almost promise a 6 week neg will not change.  Get a final test at 90 days and stop testing.

whatever it is...a test at 3 months is the recommended one..6 weeks is very encouraging..

6 weeks should be fine. Here in Australian STD clinics (or at least the one i went to) they told me that 5 week test results are 95%+ conclusive, also, the doctor and nurse said they had never seen anyone seroconvert past this.

Good luck if you decide to get tested at 12 weeks though :).
