Question about trying to conceive with PCOS

M. 🌻 • PCOS & Pregnant with our rainbow 🌈❣️🌻
So, I'm doing my first round of meds this month,    I'm almost done with school but in the mean time I'm a server and the work can be extremely physically demanding. I'm usually working large sections & lifting 60lb trays and walking an average of 5 miles a day when I work. 
My question is should I tell work I need smaller sections/need to take it easy to have less risk of losing a pregnancy? Or is it okay to be working so hard? I just don't want to do anything to hurt a potential pregnancy.
