should i tell interviewer im pregnant?

i’m 34 weeks and sometimes if i wear like a bigger hoodie you can’t tell. i applied for these cna classes (paid if u work for them after) near me so i can get experience as im a nursing major. they reached out to me about classes and i go in for an interview tomorrow to “talk about next steps.” my health has been really bad (i have a lot of fainting spells/episodes) my entire pregnancy but i didn’t want to lose out on an opportunity for a job. when i go in tomorrow would it be inappropriate to ask if i could take the classes now but start at a later date? im due june 3rd so i could probably start working the end of june once my health is better.
