[|AI|]  Hallow Dear, The ultrasonography estimation of pregnancy may have some variation for about few days during early phase of pregnancy. However, the serial ultrasonography reports are indicating that your ovulation and conception could have been around June 13. However, you did not have any sexual relation between May 19 and June 27. This size does not match the conception on May 19 also. Did you have any sexual intercourse on or around June 13-15? That period seems to be the day of conception. The other possibility is large baby which has been conceived on June 27 or small baby conceived on May 19. The later possibility is remote. I would advise you to wait for a couple of months to assess the age of gestation since as the pregnancy advances, the period variation in ultrasonography minimizes. If you are so keen on ascertaining the paternity, you may opt for DNA test. I hope this helps you.
