I would personally because you being pregnant and them not knowing they're not insured for you, also they may be inclined to take it a little more easy on you (duties and hours wise) and provide equipment to help you cope better, when I worked at TK Maxx and was pregnant, they provided me with a chair behind my cash register as I was a cashier and sometimes on my feet for up to 12 hours. they were also lenient when I called in sick and allowed me to take longer breaks and lots of toilet breaks oh and we're fine about me taking time off for appts, I didn't think they'd be so kind tbh because they were very difficult with their demands prior to me being pregnant xx
