Wrong date I’m 4 weeks 3days roughly

Nicola

So because I diabetes type 2 , I had to go have a scan done ... only to be left scared and worried by them as they couldn’t find a heartbeat . So she called someone else in to check only to be told it’s far to early and they want me back in 2-3 but to then be asked am I cramps or bleeding . I’ve never been so scared,worried stressed and upset like that in a long time . Has anyone else had the same ??? Did everything turn out ok ?? It’s really stressing me out ... would they tell you straight away if something wasn’t right ?? Could they tell that early on ?
