Is it okay to wait until 10 weeks?

Ericka • 30 years old. Married to my best friend 12/2010. Baby girls born 2016 & 2018... Hoping for a third 💕
I'm five weeks and one day and nobody will see me until July 20th (I've called several different hospitals/offices). I see all these other women who are just as far along as me and are already going to the doctors or are going very soon... I don't get it and I'm super frustrated. I know usually you don't get seen until eight weeks but why does everyone else get in so early??
