i had a scan at 6weeks exactly and i brought my picture home... a day or 2 later i spotted something which i am not sure what it is... as the worrier i am iv started to wonder if it could be a twin? which twins would be lovely but i am already high risk due to incompetant cervix... im sure its not but can anyone see what they think.. the tech said nothing but iv seen many say they was missed on scans etc coz if its not i dont know what it could be.. iv also thought maybe a twin that stopped growing... here is the pic...
