Just got my bfp! But...

Destiny • 28💋Married 💕mamax2🍼pcos🌸

So I got 2 bfp on Monday and I had blood work done Tuesday. I just got my results and they’re positive as well but they said that I’m very early so they might have me wait a week and get blood work done again...why would I have to do that though? A positive is a positive right? Help I’m nervous now 😞
