Your DUO test at 4 weeks post exposure is virtually conclusive, and as mike_no has stated, the results are unlikely to change at 6 weeks. Testing again at 6 weeks is more for peace of mind, so it's worth it for that alone. I'm sure you know this now, but if your partner is HIV+ you absolutely MUST use a condom.
Condoms and dental dams can HELP prevent transmission, USE THEM DURING ORAL ANAL AND VAGINAL SEX INCLUDING ORAL/ANAL (rimming) contact.
Hey guys, got my results today. It was -ve. My exposure was on 10th April around 8 pm. Got tested today at 8 am. Have I cleared the window? Also, the doctor told me to go for another test at 3 months...is there any logic to that?
Will that be absolutely final or would I need to test anymore?
Ok, it will be 6 weeks day after tomorrow
Your result is highly unlikely to change, you could take a final one at 6 weeks for a conclusive.
Was the sex protected or unprotected?
