due dates

So I switched OB's today and I think I'm going to like them alot better. Especially since I now only have to go to one office instead of two. Before I had to go to a separate office to see the high risk drs. So originally, I was told that my due date was March 5th. Meaning I'm 17 weeks. Then it got changed to 18 weeks bc baby was measuring a week ahead. Now the new dr said 18w3d!! Im really really small and can't help but think this is going to be a big baby so my chances of having a vbac are very small. Anyone else have this happen to them??
