is cleaning and doing chores safe ?

Drea
Don't know how far along I am I'm either 
4w3d or 6days or 5w and 2 days but is it safe to do normal chores such as cleaning my house and stuff like brooming, mopping, cleaning toilet and stuff like that? I know the chemicals are bad so Ima start wearing a mask lol but since I get tired easily will this affect my little one?  I've head that it's bad to be doing a lot of things and not to stress myself and not to be around chemicals but I don't wanna pay a lady 100$ to clean my house lol
