Measuring further along??

Brittany

Today I got my belly measured for the first time while also doing my glucose test. I’m 28 weeks on Friday and according to the doctor, I’m measuring at 29 weeks. For the mommas on here, did this happen and then still able to have a regular vaginal delivery? This is my first baby and c-sections honestly terrify me. And I know growth varies from week to week, so is it something that’ll effect birth weight?
