No lubrication during sex?

Alina🍒 • Happily married. Baby boy was born 12/17/2015 and our little girl got here on 04/03/2020 ❤️
I am almost 7 weeks pregnant and o am starting to get my sex drive back a bit. The thing is, even though I do get turned on and want to make love to my husband I get zero natural lubrication( is that normal?
