Potential retaliation..?

This is truly the only place I could think of to vent / ask about this. So I’m due mid April and I disclosed to my job in mid August that I’m pregnant. I told them early because I was SO sick and I didn’t want to get in trouble for leaving the sales floor constantly for bathroom trips. This seems to have backfired on me BADLY.

I was given my employee review at the very end of September and it was the first awful review I’ve ever gotten at this company. I’ve worked there for over 2 years now and twice a year I routinely got “exceeds expectations”, wonderful comments from management and corporate along with good raises. This one I got “needs improvement” and no raise. They told me I was unreliable and I guess needed to work on my attitude..?

I took it hard but I got over it.

Now today I got another review and it was even worse than the last one. This one in particular says that I neglect all duties of my job and leave extra work for my coworkers to pick up. Also says I’m no longer a “team player” ? I have never been corrected on anything at work and have been told frequently by my manager that I’m doing well. I’m considered high risk and have had awful swelling so I’ve definitely been moving a bit slower than I used to but I have good days too. I’m just at a huge loss.

I was also silently demoted in October from a key holder to basic supervisor with no paper trail. I have no idea what I’m doing wrong but I’m not getting a raise again either. I want to quit so bad but I’m so close to maternity leave. I legitimately feel like I’m going a bit crazy here.
