Hi there i wonder if anybody on here can help me with this. i have had a 8 week scan and a 12 week scan so far. both of these scans say i concieved around the beggining of may (this year). i dont think there is, but do you think theres any chance i actually concieved on march 12th? its like a 7 week difference... could scans be wrong by this much? Thanks for any help xxxx
