3 months is conclusive no matter what the risk.
i read online and ask drs about it, 25 days ia average.
best is first test at 4 weeks/ 1 month. which is 90% accuracy.
for those at vv high rish or doing some chemo theraphy, get retested at 12 weeks/ 3 months for conclusive.
test at three months for a conclusive result
25 days test is pretty relaxing. But not conclusive, i think. Do a test after 12 weeks.
