Day 3 blood tests questions

Ch

Hey all,

I had a miscarriage at 10 weeks in July and my period still hasn’t come back naturally. I’m currently on CD 45 and my doctor has ordered the blood tests that are traditionally meant for CD 3. She said she wants me taking the tests ASAP. I have two questions for you, I would have asked my doctor but we’re just emailing and it’s past office hours:

1. Will my results be skewed because they’re not on day 3?

2. Do I need to fast?

Thanks ladies.
