After a run of three home games in the space of a week, Pompey now have to contend with the same number of fixtures on the road.
But Clark Robertson believes there is enough character in the squad to deal with such a hectic schedule.
They have a midweek trip to Crewe to contend with first, then visit Ipswich and Plymouth in quick succession.
And Robertson is not looking past the clash with Railwaymen as the Blues look to build on their six-match unbeaten run.
Pompey’s skipper said: “Everyone knows that the squad is small at the moment and we’ve got a few injuries to deal with.
“But we’re pulling together and we’re all going to have to play at some point in this busy run of games.
“They’re coming along thick and fast at the moment and the manager’s having to rotate the squad to deal with that.
"It’s important that we just continue to take one game at a time and then see where that leaves us at the end of the season."
“That keeps everyone involved and I do think the spirit and togetherness we’ve got right now is unbelievable.
“When you’re on the kind of run that we are, you just feel really confident whenever you take to the pitch.
“But it’s important that we just continue to take one game at a time and then see where that leaves us at the end of the season.
“There’s no point looking at the league table right now and we’re only focused on facing Crewe on Tuesday.”
Pompey thrashed Accrington 4-0 at Fratton Park on Saturday, despite Marcus Harness being sent off midway through the first half.
Robertson said: “They are a big, physical team and it’s always going to be a struggle when you go down to 10 men.
“If that had happened earlier in the season then we might well have folded, so it shows the character and mentality in this squad right now.
“I thought we managed the situation really well, scoring from a couple of set-pieces and also hurting them on the counter-attack.”
