Ugh. I'm what to do.

Please no rude comments. My mom got me a job where she works. I tried to get hired there before but couldn't do the job because my wrists were giving me issues. I got what I think is a fix. I haven't had any issues. I started this job on Tuesday. Its seasonal with most likely becoming permanent. I absolutely HATE this job. I'm in so much pain because of it and my wrists ate starting to act up again. Also I'm trying to get pregnant and I don't think it's a good job to have when pregnant. It's very physical. i told my mom how much I hate it and she said she wants me to finish out the 90 days because she got me the job. I am sick thinking of going in tomorrow. My mom is off tomorrow. I want to call off and/or quit.
