I'd definitely keep an eye on it. I posted a similar thread on here a few months ago. My mates water pythons did the same thing, she shed, then shed again, and again and again. She shed a total of about 7 times in 8 weeks.
She was taken to a 'reptile vet' in Karingal and was told that it was fine. The vet did no tests, nothing. a few weeks later the snake was dead. Her skin deteriorated so much that it was flaking off in your hand and exposing flesh. cracking because it was so dry (even tho the humidity was fine in the cage)
so keep an eye on her, and if she sheds again then definitely take her to the vets! and if they say its normal get a second opinion.
good luck with it and let us know the outcome.
