Ben Thompson conceded it was one of those days as Pompey surrendered their unbeaten League One record.
The Blues failed to sparkle at a wet Fratton Park as they this afternoon slipped to a 2-0 defeat to Gillingham.
The Gills’ secured their a first win in all competitions since August 11 courtesy of two goals in the first half.
Tom Eaves and Alex Lacey’s strikes created an unassailable lead, despite the Blues’ improved second-half showing.
That coincided with Thompson introduced off the bench along with David Wheeler at the interval.
And the Millwall loanee admitted little went the Blues’ way.
He said: ‘We’ve been on a fantastic run , you can’t keep it going the whole season, you are going to have days when it just doesn’t quite go for you.
‘Today was one of those – nothing was falling for us, the ball was going over, wide, hitting players and it didn’t drop for us.
‘We have to carry on, keep the form going.
‘It’s only one loss in 12 games so there's no reason why we shouldn’t keep our heads held high and go into Monday’s training and be ready for next week.
‘It didn’t go our way, we were playing all right football, throughout the game were on top most of it.
‘We gave away a couple of goals we shouldn't have, that’s football, it’s not going to go for you every week. You’ve just got to take that on the chin and learn from it.’
