Hi all just wondered if anyone else has had this before........was told today at 12wk scan im only measuring 10weeks. which is fine i had suspicions as my cycles are long. but instead of giving me dates she said id have to go back in 2weeks for the routine 12wk scan to find out. This has got me worried slightly as i was only 10 weeks at scanning my first child but i didnt have to go back until 20wks. im prob over reacting because baba was moving and there was a heart beat.......just very confused why she couldnt give dates etc today?
