My advice..... take the earliest scan you can get!!!!!!
I didnt have a scan till 16w, and that was due to a small bleed..... more due to a stressed out mum2b!!!!!!!
otherwise, my first u/s would have been at 20 weeks!
I wish I had have pushed for an early u/s, as my dates are completely stuffed now, due to not having any u/s in first 12 w.
Early u/s are not usually due to any huge probs. Enjoy seeing your little one for the first time!!!!! Cos it really sucks having to wait!!!

Enjoy!
