Measuring 2 weeks ahead...

Hi I’m 28 weeks and measuring 30 weeks. With my daughter I never measured ahead . Does this mean I’ve gained too much weight? I seriously feel like I eat less now that I’m pregnant than I did before pregnancy. My iron is 6.2 and she said she’d like it at 12.5 ? Also I have some pretty bad swelling she wants to keep an eye on. She also mentioned the baby feeling breech. Idk but my whole pregnancy I’ve been worried about gaining too much weight . Could I be measuring ahead Because I’ve gained too much weigh?
