Hi all
I read combo test after 6 weeks is not good because antigne disappears thar's true ??
I test combo ab an p24 afte 90 days 3 month .nonreactive .ineed test again??
Oral, anal or vaginal and did you use a condom? You don't understand what you read. Duo is conclusive after 4 weeks because it looks for 2 things, so you wasted your time testing again.
