Blood Screen Test

Isn’t possible too find out sex of the baby through this or do I need too do a completely different blood test.

Just wondering I would really like too find out ASAP so I can plan for baby, I had a ton of boy clothes and I just wanna know if I gotta get em out the loft (my mums house) before I start too buy everything else, also I have a 2 year old and I’m tryna get him into nursery and I also recently moved into a new flat so am buying stuff for here, so a lot too happen in such a short space just need options that give a high chance of being true

I’m not into them early scans cause a lot of times I hear they are wrong so I’m very worried and my son didn’t show us what he was till I was 28weeks so I don’t wanna waste money as I really don’t have a lot 😫
