I have a serious work related question! Please help!

So, I work at Home Depot. This April will be my year mark. I’m 9 weeks pregnant. I need to know my rights with work. I work at customer service. I can’t lose my job especially now that I’m pregnant. Please be honest with me. Will they let me go? Should I start looking for another job? Or am I safe? I actually don’t mind working for Home Depot. I don’t want to lose my job. I have two kids that I’m loving on and taking care of currently and I go to school. I can NOT lose my job!
