How do you feel about burning incense sticks while pregnant?

Cierra

I am 10 weeks and 3 days pregnant and my boyfriend feels like he need to light a incense every freaking day all day . I keep telling him don’t do it until I ask the doctor is it safe but it’s just like he does not care and lately he has been doin things without thinking about how and if it would effect the baby and honestly I can’t evn stand the smell🤢🤢... I just want to know what do y’all think about it? Is it harmful? or is it ok ?
