Pregnant working moms

Okay so I’m only 6 weeks but the sickness is horrible. I am way more sick at work due to the smells and the fact I’m having to have my head in a public restroom right after someone takes a shit or on their period which makes me throw up more. I talked to my boss and HR manager and all they said was I can request to be put on a temp unpaid leave but they have the right to deny my request. I also mentioned to them, “why can’t I just work from home untill I can find a medication that works for me?” Their response was just “we try not to have many people work from home.” I know I’m not the only one so what did you guys do or how did you guys handle it? I’m so frustrated and I just feel like it’s not fair at all.
