THank you Kate for that info!

I wasn't even going to have it done but then i had some spotting basically due to having sex the day before and i had a little bit of spotting the next day. I was told by the DR at the hospital that my cervix was fully shut and wasn't coming from where peanut is, but my GP has kinda insisted that i do the NT scan as sometimes spotting is due to abnomalities, i guess she is just doing her job! At least i get to see peanut again before my 19wk scan!
