Pregnancy and second hand smoke

Hello,

Need some advice. I live in a building and my apartment constantly get smells of cigarettes, In the bedroom, in living room. It’s like someone is smoking near me. I don’t know who it is but I know this building has a lot of smokers. I am incredibly frustrated and know it’s super toxic but now I’m pregnant and it’s stressing me out. Any advice anyone was in a similar situation. I know moving is best and I’m working on it but it’s not a quick task. This situation is quite upsetting and giving me a lot of anxiety. As I am sitting here it smells of smoke in my apartment.
