Anyone else needed a 32 week scan???

Lauren
:( I had my 20 week scan on Thursday and was told everything seemed fine.. then I got a voicemail thismorning to contact my doctors as soon as possible.. I called and spoke to the nurse and she said the doctor has requested that I have a 32 week scan. 
I asked her if something was wrong and she asked if I have been experiencing pain in my lower abdomin? I said no and she said the doctor hasn't given her the exact details but would like me to have a 32 week scan and to book an appointment with him if I would like to discuss it..
