Requesting vacation time

I just changed jobs. I have 3 vacations that have been booked since January. Everything is paid for. Including flights. I am going on one vacation with my bf and his family. One with my family. And then my bf and I are going on one alone.

When I switched jobs, I asked the manager how much vacation time I will get and said I’m going on vacations. He said he didn’t know how much time, but would find out for me. He never told me

I put the days in the system to request all those days off. They aren’t until July , September and October. He hasn’t accepted them yet.

I’m nervous that he’s going to tell me that I can’t take those days off. My family would be mad at me.

What should I do ?? I really want to go on my vacations.
