Hi, I have just been for my dating scan as I have PCOS and only know I had my LMP in February but not sure when...so had to be scanned as quickly as possible to determine dates. Well I am just 5 weeks and 3 days along and they were only expecting to see the Gestational sac, but after she pointed out the sac she zoomed in and said that she could see my baby and then she saw a pulsing movemet too....yes you could actually see the heartbeat....this was all too much for me....I just burst into tears...Soooo precious!!!!
