Birth Control

I just started 28 day Sprintec a week ago, I've been on it, taking it in the same 10 minute window for a week and 3 days. When can I have sex without a condom? I read online and about half say to wait a month and the other half say you only have to be on it a week. Our 1 year is coming up really soon, and we're both virgins, I want it to be really special the first time, I got it so we didn't have to use a condom, but I don't want anything to happen on our first time either. Any help would be greatly appreciated.
