Pregnancy discrimination

Okay...

So I started CNA classes last week at a care center, and during the process of applying, the teacher said that I could possibly work there and have the center pay for the classes. When I told her that I was pregnant, she went into how I would need a note saying I could lift a certain amount of weight to even take the class, and to work there. Which I understand... But then she told me they weren't even hiring right then, and that I probably wouldn't be able to get a job there because I am pregnant, and if any positions opened up she would let me know.

I didn't think much of it, until the first day of class, two women mentioned that they applied for the class the day before the class started and were also going to be working there as CNA's so their classes would be paid for, and they would get paid for their clinicals. The teacher never mentioned any openings to me, and still hasn't asked to see a note of any kind for the classes.

Was I discriminated against because I'm pregnant? Because I still go to the classes, I'm still doing the same work they're doing, and I'm hardly 13 weeks pregnant. Did she not hire me because I'm pregnant? I know legally it's not okay for her to do that, but I'm not sure how to confront her with out making things weird in class.

And will I be able to get any work once the classes are done? I've heard of many women working up until their due date, but will I even be able to get hired anywhere?

Sorry... It didn't really bother me until last night. Any advice anyone could give me would be great!

Please help! Thank you in advance.
