I had one last week for the same price, and it was defo worth it!!
I got to see a little kidney bean shape, but you could see the heart beating like mad, which was the best (and most reassuring thing!). They also checked my ovaries, womb lining, etc, so everything looks ok. Hubby came with me, and for the first time, got a bit emotional, as it was the first time it seemed 'real' to him.
Ive still got another 4 weeks untill my 12 weeks scan, so couldnt have waited much longer!
It doesnt take away the worry though - mines back again now, lol!
