Need opinions on being pregnant with different sex and early gender test

Cherie.

Hello, I have two girls and with both of my pregnancies in the early stages I was very sick for month. I’m pregnant again and thankfully I haven’t been sick yet even tho I’m only 5weeks. I’m wondering if there is actually a difference between being pregnant with a girl then a boy and what they are. Also thinking about doing an early dna test to find out the gender at 9weeks if anyone had done that let me know also. Thank you.
