Jagielka would have been delighted after being given the nod to replace the injured John Terry before Tuesday night's game at Wembley.
But the Everton defender's joy was short-lived as Ukraine threatened to pull off a shock victory until Frank Lampard's late penalty snatched what could prove a vital 1-1 draw.
The result nevertheless saw England surrender first place in Group H, a position they should reclaim next month when they host minnows San Marino.
A tricky trip to Poland follows four days later and victory there would ensure they end 2012 with at least a share of top spot.
Asked if Tuesday night's performance and result were merely "okay", Jagielka said: "It's probably the right word to use, 'Okay'. No great shakes.
"We'd have loved to have had the full six points but four points will do.
"As long as we continue building on it, we'll be fine."
He added: "Definitely one point gained.
"We look forward to the next game now and if we can make that seven then it's a progression and hopefully we'll finish top of the group."
Ukraine outplayed their opponents for large parts of Tuesday night's game and asked if England had "got out of jail", Jagielka said: "Yeah, a little bit.
"But if you look at the chances we created, two or three pretty clear-cut ones in the first half and a couple more in the second - hitting the post and stuff - as much as the performance wasn't amazing, we still showed glimpses of being able to create the chances.
"If we'd taken them, especially earlier on, we'd have been in control of the game."
Most of those chances fell to Tom Cleverley, who had a nightmare on his first England start at Wembley.
Jermain Defoe also saw a goal disallowed, with referee Cuneyt Cakir repeatedly penalising the home side for raising their arms.
"We're winning the ball and the ref's either booking us or giving free-kicks," Jagielka said. "So, a little bit frustrating but there's not much we can do about that.
"We've just got to keep going until the final whistle.
"Being 1-0 down with 10 minutes left, we'd have taken the 1-1."
He added: "Thankfully, we managed to keep plugging away and get the penalty.
"Frank was calm as you like, finished it off, and a draw's not a bad result at the end."
