Answer
A gestational sac larger than normal can be a sign of excess fluid inside the sac. But it is too early to say weather this is just a one time anomaly or is there some problem with the baby. Also remember that USG is very much operator dependent and therefore not 100% accurate. Therefore in my opinion it is best to wait and undertake another scan between 14-16 weeks to rule out any problem with the baby. I understand your concerns and would like to give you a concrete answer. But the nature of pregnancy in the first trimester precludes me from giving you a concrete answer. Anyways do not fret about it. I hope and pray that your baby should be fine. Feel free to ask me any further clarification if required.
