Despite controlling the game for long periods, Parkinson's men had to settle for a point last time out following Gillingham's barely-deserved injury time leveller through substitute Antonio German.
As frustrating as the last grasp Gills goal was for Parkinson and his squad after the game though, the City chief insists there has been no focus on it in the build up to this weekend's encounter with Orient.
Parkinson said: "We discussed last weekend directly after the game and we have moved on from it now.
"When you concede late, it always feels like a defeat, but that is football sometimes.
"We have put it to one side now and prepared as best we can for Leyton Orient this Saturday.
"We have done our homework on the opposition and we are looking forward to playing as well as we did last week.
"If we can get the result on Saturday then it makes the Gillingham point look a good one.
"No results are easy to get this season so you have to work extremely hard for every point you can get.
"We are in the mix at the moment in terms of teams who are picking up points fairly regularly but we are striving to get a run of victories together.
"Unfortunately we didn't get the victory last Saturday but we will do everything we can to give us the best chance of winning this Saturday."
Opponents Orient head to the Coral Windows Stadium currently in 19th position in the League 1 table.
The O's came agonisingly close to securing a place in the Championship during the previous campaign though - losing in a penalty shoot-out in the play-off final to Rotherham United - and a lot of the players from that team from last season remain at the Matchroom Stadium.
Parkinson added: "The results in this division are a bit topsy-turvy so far this season.
"If you look at Preston, they lost three on the spin and then went to league leaders Bristol City and won. Bristol City themselves were unbeaten for a while and now have just lost two on the trot.
"Bristol go to Peterborough United on Friday night, Peterborough have only one point out of fifteen recently despite being heavily tipped at the start of the season, so it is a very up and down division.
"In this division, I don't think it matters where the team is in the league at the time you play them.
"We have won at Preston ourselves but we couldn't win at home to Gillingham. I don't think league positions make too much of a difference to a certain degree, especially given the competitive nature of this division this year.
"We have identified a couple of key players that they (Leyton Orient) have got and we have worked on how to nullify their threats.
"We have also concentrated on our own work and the players who we think can cause them problems.
"We want to continue to play some of the sort of football we played last weekend, especially when we were going forward and making chances.
"We have created a lot of chances this season - home and away - against some top teams and some teams further below. We want to continue to do that and the lads are in confident mood."
