Pregnancy help? I’m confused!

Hey guys! So something happened today, I found out I was pregnant! I had a positive test at the doctors! She said I was maybe a couple weeks along due to my last period.

They told me to go and get blood taken to see how far along I am.

I get done and I wait literally what has seen like all day for the call.

I got the call and she said u was one week pregnant?

What?..

she said wait till my OB appt. which is the 22nd of january.

It has been racking my nerves all day..

She said that I was either 1 or 3 weeks pregnant that the thing almost looks the same and that they’ll be able to really tell me on the 22nd.

The pee test was a quantitative, which is most accurate. On the results it was a 47 with 14 DPO.

I’ve done some research where some people were in the same boat as me.

Said there’s almost never a negative and always if it’s positive then you’re pregnant. I was supposed to start my period three days ago. But Ive been showing 3 week pregnancy signs.

What do you guys think? Has anyone ever had this happen before. I’ll be a first time mother and just overly excited!
