Safina has been battling a long-term back injury and haS been on an indefinite break from the game.
The Russian has repeatedly suggested she may never return to competitive action and her brother Marat Safin claimed yesterday she had retired.
However, the 25-year-old later responded on Twitter and insisted she had not yet made any decision about whether to quit the game.
She tweeted: "My sweet tweeties, I didn't make any official announcement.
"Give me please some time and I'll let you all know...Right now I want to take care of my back.
"On Tuesday I'm having a treatment...Once I decide something you'll be the first to know, I promise!! Love you all."
She added: "Thank you for all your messages, they really mean a lot to me.
"You are everything to me my sweet twitties."
Safina has claimed 12 women's singles titles during her career and rose to the top of the rankings in April 2009.
