I painted a whole 1 BD apt during my last trimester with my second baby and he is more than fine, go for it
I did with my second. As long as there is ventilation and fans u shld b ok. If the fumes get too strong for u jst wear a mask. :)
I was told by my doctor it's okay if the room is well ventilated, which it sounds like it will be. Just make sure if you get light headed or anything take a break and get some fresh air. I painted the nursery when I was pregnant with my daughter, she is fine and I just painted the new room for this baby last week. It was like it needs to be done so I gotta do it. As long as you feel up to it and take a break of you need one, I say go for it.
