There is standard on how long you should wait before breaking no contact. If she's talking to you again, it means that she's ready. However, the question is, are you ready? Here are signs that you can watch for:
1) Do you feel that you've recovered completely from the break up?
2) Do you still have false hope that you will get back together?
3) Are you over-analyzing all her actions and all the signs?
Until you have recovered from the breakup you should continue no contact. Take whatever time you need before you start talking again. At least now you know she's ready, so you can contact her anytime. If you were meant to be friends, she will still be around when you've finished the recovery process. So there's no reason to rush.

She already told you that she needed some time away from you. She could have easily ignored you. The fact that she's talking to you again means that she's done her recovery, whether the 3 months have passed or not.
But like I said, it's not about her at this point, we know she's ready to talk to you. It's about whether you are ready to talk to her again.
