Got a sooner appt

So I called the local midwife's and let them know I'm pregnant and they said they could see me as early as sep 7th which is not that far away compared to the first appt I booked with the obgyn on the 20th. I'm trying out the midwife's cause I really want to go the all nay route if I can. I told them I'm not 100% sure when I ovulated I have an estimate not when I could have and they said that's ok. So looks like I will get checked out sooner I'm hoping they give.me a dating scan or at least order one since they are part of the hospital wing here.
