Hi Teak and everyone in this forum. I don't understand why some doctors recommended eight weeks and some three months and some six months. Let say if eight weeks negative then positive at three months who responsible for this matter? Or if three months negative then turn out positive at six months who responsible for this? Why all specialists and doctors not unanimously to set one conclusive window period or maximum conclusive window period? And what is the real windows period at the moment with high risk expose? Thanks!!!
