i know 10weeks is strongly proved u are negative but not 100%sure,for a better health screen repeat @12weeks for a peace of mind.
Where did you obtain your information?
i heard that 10 weeks is enough, so why 3 months?
You Can Relax If your 10weeks test is negative and remember for the final test 12weeks.
please use a protection.
keep safe.
If you had a real exposure obtain you 3 month post exposure test.
