Is it normal to not get a 12 week scan?

Cali

Because i was under the impression (ftm so im clueless) that this is when they do the NT scan but when i went in they just listened to the heartbeat and thats it my next appointment ill be 17 weeks only have had the very first scan at 8 weeks, was i supposed to schedule this myself? I feel like they should have informed me of this because they know its my first. Is it ok that i didnt get it?
