Possible big baby?

Molly

So I had my appointment and the baby is fine but he or she is already 3 ounces for 12 weeks 6 days?? Like am I going to have a big baby? It scares me because my body cannot handle pushing out big babies had a C-section with my daughter all because she was 7 pounds 14 ounces. I have issues even pushing out 5 pound 5 ounce babies.. please someone if anyone have issues like I do when it comes to giving birth how much did your baby weigh already at 12 weeks almost 13 weeks. Just looking for advice thank you.
