My son is autistic, and can be very defiant. I did wonder at one point if he had ODD. I listened to people for years telling me his behaviour was normal for his age, or he was emotionally immature but would catch up, or he couldn't be autistic because he made eye contact, or that the problem was my lax parenting etc etc.
This put me off seeking a diagnosis, I let people convince me I was overthinking. But the older he got, the more obvious it got, to me, anyway, and eventually - and with the help of experienced mums of kids with SEN here - I felt confident enough to seek diagnosis. He was diagnosed with high functioning autism (what they used to call aspergers) when he was 10.
A friend of mine with an autistic DS was put off seeking diagnosis by teachers and friends till her DS was a teenager, he wasn't diagnosed till he was 14. I must admit, when he was little I can remember judging her and thinking his sometimes difficult behaviour was down to her parenting. I feel deeply ashamed of this now I've been on the other side of this.
So, although they mean well, posters telling you your DD's behaviour is normal for a teen possibly aren't that helpful. I mean, it's certainly possible there's no SEN, it's just hormones and she'll grow out of it - but I'm sure you know that already. If what you're asking is, could it be possible she has undiagnosed SEN, then the answer is yes, it could be.
