What can I do?

I’m in my 3rd trimester and new tenants moved in below us. They just moved in yesterday and the smell of marijuana is ALREADY coming from their apartment into ours. Their bedroom is below mine and my daughters crib is in my room. I’m so upset. I just emailed my property manager but they won’t respond until Monday at the earliest. Is there anything else I can do to survive the weekend? I’m so angry but don’t know what kind of ppl they are so I won’t go to their door.
