I just had my first ultrasound..the doctor dated me at 8 weeks along and my conception date at 7/18/13. I just moved where my boyfriend is on 7/25/13. I didnt have sex before that and my periods have always been irregular (not on a 28 day cycle). I know I conceived on the 25th but my bf thinks I slept with someone before I moved. Ive dome some research and theres a margin of error of 5-7 days. The doctor didnt factor in my blood work with the date. Is it possible the doctor estimated wrong?
