Blood drawal

So I am 7 weeks pregnant! I have my first appointment next week hitting 8weeks! I know they will have to draw blood. I have an extreme hemophobia (fear of blood). I don’t mean to, but seeing blood or veins or even just the talk of them make me pass out. I have tattoos so needles don’t bother me. I’ve never given blood before or had my blood drawn and im excited to see my baby but so scared of this one certain aspect of the visit. Does anyone have any advice on getting over fear of blood or how to not pass out or anything they had to deal with it?
