Pregnant 😟😟

So I’ve just found out I’m pregnant 😟 I done a test two days before my missed period and it came back negative. I’m now five days late and taken another test which has come back positive. It came back positive basically straight away before the dye had even gotten all the way across the stick. The lines are so strong. What I’m wanting to know is does this mean I’m further gone than two weeks? I’m planning on getting a clear blue one that will tell me how many weeks as there are two people in question on who’s the dad. And can the drs also tell by a blood test? as I’m hoping to get an appointment tomorrow and ask them.
