Hello,
by this stage of the pregnancy your conceived date cannot be accurately determined.... it seems your baby is measuring ahead by 1 - 2 weeks.
You would have conceived your baby within about 2 weeks after your last period on 3rd May. Don't worry about the date from your Obe - these are just an estimate based on the size of the baby.
Best wishes to you.
O yea I also have three huge cyst on my right ovary and a small one on the left
