Pregnant or drugs, i think both are pretty stupid
To get pregnant at 16, with a promising tennis career ahead of her..... how stupid can you get? She should have used the correct protection etc. because IMO getting herself pregnant at 16..... pretty careless and stupid.
And if it is drugs, then yup.... stupid too..... but i think 2 years is quite a fair punishment.... at least she's young, and could come back when the ban is over, being only 18.
