Hi i dont think u need to panic, it happened to me few months ago, i had just given birth and the 1st xray was not clear COZ my boobies were so congested. I was sent to room 118 2wks later and they told me I need to redo another one they gave me a trainee and she had to repeat like 10 times. I was so pissed off but had no choice but to act as if everything is okey though its my body she was putting at risk. Finally everything was okey.
