In a couple days I will be starting a month long CNA training course through a facility where I will have a job right after, but I just found out that I am around 7 weeks pregnant. I've been told by a nurse who used to work there not to mention the pregnancy until after I get my certification as there have been girls who have gotten fired, but I'm wondering if I should tell them while I'm still in training so maybe when the time comes that when I do start the official CNA position, they can accommodate me accordingly. My clinicals for the class don't start until towards the end of the month, so I don't think I'll really have to do any heavy lifting or anything strenuous (besides CPR training maybe (?)) until then and when that time comes I'll be somewhere around 3 months pregnant. I don't want to come into a new job and a good opportunity like this and already cause complications with my new employer.
