Edinburgh was left frustrated after his team failed to end a dismal run of nine home games without a win as they lost 2-1 to play-off hopefuls Plymouth.
He said: "We now have to strive to get as many points as we can from now until the end of the season, then re-evaluate and have a busy summer."
Chris Zebroski scored for Newport to pull them level after Tyler Harvey had given Plymouth the lead after 20 minutes. Conor Hourihane gave John Sheridan's the three points when he fired the ball into the bottom corner after half an hour.
Edinburgh added: "Again we've been beaten by the odd goal.
"We shot ourselves in the foot by conceding goals that could have been avoided but our goal was a very good goal. But I'm getting tired of repeating myself.
"It's endless the amount of games we have lost by one goal but when you're chasing games like we have this year it is difficult to get back into them every time.
"That's the frustrating thing for me, as good as our early home form was this season it's been difficult since the turn of the year, on a bobbly pitch. It's not the cause of all our problems but it's not conducive to playing the football we want to."
