Paul Trollope's side snatched a stoppage-time equaliser at leaders Brighton to draw 2-2 and held second-placed Charlton 1-1 last weekend.
Higgs told the club's official website: "Although I would have gladly taken a point from both Brighton and Charlton, I cannot help thinking that we could have come away with at least four points from the two fixtures.
"But these two games have definitely given us a platform to build from and hopefully we can take that forward and push on with our season."
Higgs added: "We now turn our attention to Tuesday's Johnstone's Paint Trophy area semi-final match against Exeter.
"We're now just three games away from a trip to Wembley, so we must not underestimate the significance of next week's tie."
