Is it too early to go to the doctors?

Lisa • Wife of 2 years and first time mamma to be 💑
I got my BFP nearly a week ago and took another 3 days ago which told me I am 1-2 weeks. Booked a doctors app for Friday so by then I will prob be 3 weeks... Is that too early yo be seeing the doctor? I have missed my period too. Don't want to get carried away.. Any help/advice?
