The mother-of-two took to Instagram in a lengthy post, explaining that the photos don't show the two doctor's visits and all the medication she is currently on.
"I’ve already been sick twice (kids as well)on this Australian tour, but the first time we got sick, I was able to push through," the singer wrote.
"What these parasite paparazzi don’t show you, is two doctor visits in Byron on two consecutive days, antibiotics, steroids, Vick’s, nose spray, throat spray, more steroids, NyQuil, a screaming baby in the middle of the night, every night, while mama gives him warm baths and tells her daughter everything is fine," she continued.
"I have never phoned in a single tour, I have an impeccable record for not cancelling. I mother with everything I have whilst handling all the rest."
Fans quickly jumped to Pink's defence, with one fan writing: "Your real, true fans know exactly what kind of person you are and to cancel would've been a hard but necessary thing to do"
"You should not even have to defend yourself. Everyone knows you have been fighting illness and you have two young children. All of your true fans understand!" another commented.
Justin Timberlake, who has performed with Pink twice, also left a message of support: "As a parent on tour as well, and an artist who LOVES their fans just as much and wants to give them an unprecedented experience... AND is currently battling an injury, a sinus infection, and trying to be the DAD I want to be too?? I say HATS OFF to you, my friend. I don't know how Mums/Artists like you exist."
