Hi
I've lurked on this board for a time and have found it very interesting and informative. I thought now was the time to dive in and ask for some support. 
I have three boys and have always known DS2 (now aged 8) was different.
He was diagnosed with dyspraxia at a preschool age (about 31/2, I think). This was mainly verbal dyspraxia, but also some degree of fine and gross motor skills dyspraxia.
He's done really well and after several years of SALT his speech is almost normal. He's intelligent, funny and loving.
We all moved house/job/schools 2 1/2 years ago and he has blossomed at his new school. However, DH and I (and the school) think he shows some traits of ASD.
He has an IEP at school and we meet with the SENCO and his teacher each term. I don't think having a diagnosis will make any difference to him at the moment, he certainly won't get any more support from school.
We have debated whether to get him assessed for about a year now. Eventually, we decided to; mainly as I am concerned about when he goes to secondary school and how he will cope then. It may affect where we send him.
So, I bit the bullet and made an appointment to see the GP. He was lovely and has made the referral. He is a new GP, I think, and didn't know whether it would be a CAMHS or a community paediatrician referral, but said he would find out and get the referral done the same day.
So, now we are just waiting.
I guess my main question is what should we expect to happen from here? Mainly, I just want a bit of hand holding.
Thank you if you have managed to read to the end of my mammoth post!
Hairy.
