House of smoke pregnant

So my husband smokes weed . I don’t and I’m 6 months pregnant. At first I didn’t mind him smoking inside but as I’m getting bigger and cleaning the house for the baby all the time he just smokes where he wants . Is it wrong of me to tell him to smoke outside now. I just get so annoyed but the smell and ashes everywhere it’s gross. And I don’t want my baby stuff smelling like it .
