After the match, she told reporters: "I am happy to talk about my match but not my personal life. I hope you will understand that. I want to thank everyone for their support and sweet messages.
"I prepared as best I could. I haven't been able to play that many matches because of the [knee] injury. I felt rusty, it wasn't a pretty match."
The Dane had not lost in the first round at Roland Garros since she made her debut at the event in 2007.
