Is conception date calculation accurate when done at 7-8 weeks of pregnancy?
well, i went to the doctor to get a vaginal ultrasound on may 28 and the machine calculated based on the size of the embryo that i was 7 weeks 3 days pregnant, that means that according to that calculation my LMP was on April 6th and conception date was around the 20th of April. the problem i have is that i had sex with my ex on April the 9th and i had sex with my current partner on April 18 and 21. what are the chances that the father of my baby is my ex? Should i be more confident the father is my current partner? is hard to really pinpoint the day. Can the machine be off by a week in calculations that early in the pregancy? Thanks a lot!!!
