老板不回复我的信，怎么办？

我的maternity　leave 明年元月份就要结束了，我给我的supervisor send email and tell him I am going back to work, the date but he didn't reply my email. I have sent to him last week.

Before I took maternity leave, I only give them 2 weeks notice, my boss's boss was very angry. This is one of my best friend in the company told me. Because I didn't give them enough notice.

I am very anxious now. How should I do?
