You are probably fine, especially if you weren't just standing there breathing it in right above the drain the whole time. Were there windows open or fans going? Because that's even better. Also, it doesn't sound like you are around that constantly, so that's good. I asked my doctor about cleaning the bathrooms at home, and she said using natural cleaners is best (like vinegar) but cleaning should be okay as long as there's good air flow and it doesn't take long. But since you do it for work, maybe just ask your doctor for his/her opinion or advice. But for your question here, I'm sure you're okay from tonight.
I'm 30 weeks n i still clean with bleach etc n i feel fine while using it, if you feel at all light headed stand outside for fresh air
Same as R4ch4el88, I still use bleach etc at home and just make sure the areas well ventilated and wear gloves or wash my hands thoroughly afterwards. My dr wasn't concerned and said it was mostly some industrial chemicals that are the big risks. Maybe ask your dr for a list or something due to your job?
Thank you so much ladies I appreciate it!
