Quick question on ranked 5man placements

ok so me and my team are so far undefeated and i was wondering how many fames we have to get our rank. and also if we will be put high. we were against gold and plats the first game we won, then we went against silvers and gold players we also won that and our last game we went agasint 2 diamonds and one of which was ex masters and and 3 golds so i was wondering is that meaning that we will be in a high elo ranked 5 ? or will we start mid elo even if we are undefeated ?
