Pregnant ?

My last period was June 7-11 I was suppose to get my period on the 3 of july but didn’t. If I am pregnant I’ll be 4 weeks and a couple days.

I took a test- 2 came back faintly positive ( blue test ) and both of the pink ones came back negative.

I went and got blood work and I’ll get my results Monday but I’m scared I asked the lady some questions and she ended up telling me my doctor asked for blood work to see how far long I am but wouldn’t u just get a regular hcg test
