Wiggins, 36, had hinted the race in the city of his birth could be his last, but afterwards said he was "not sure yet" what his plans are.
"I don't know, I've still got really good legs," he said.
"This might not be my last race. This for sure is my last ever race with Mark Cavendish, though."
The 2012 Tour de France winner added that he "just wants to enjoy this moment".
Wiggins' admission follows his comments after last month's London Six Day, when he hinted he could be tempted to race there again next year.
Wiggins and Cavendish claimed overall victory in Ghent after winning the final madison event.
The pair also contested the Ghent Six in 2007 and won madison gold together at the World Track Championships in London in March.
They competed together in the madison at the Beijing Olympic Games in 2008, finishing joint eighth.
"We've had an incredible 12 years and have achieved so much together. It's been a pleasure," Wiggins added.

Customers are being urged not to eat the affected products, made in a factory on Teesside.
The biscuits, including cheese thins, shortbread, chip cookies and fudge brownies, were made by a company called Baketime, based in Middlesbrough.
"There has been no evidence of any contamination", it said.
But Baketime confirmed it had seen "evidence of pest activity" in January and again in March.
"We continue to work closely with our local environmental health officer and pest control contractor to ensure that the issue has been properly eradicated and hygienic standards on site are upheld," the company said in a statement.
Baketime, based at South Tees Imperial Food Park, said it was recalling all the biscuits and snacks as a precautionary measure. In the meantime they were being taken off sale.
The products are sold in Aldi and in small convenience stores around the UK.
The FSA said the biscuits and snacks had been manufactured in "unhygienic conditions", and that it was investigating further.
