Changing jobs at 6 months?

Maybe I'm overreacting and being silly, but I'm getting tired of my job. Don't get me wrong....its an easy desk job with good health benefits (even though I'm on pregnancy Medicaid) and my boss has been very supportive during my pregnancy. I'm just sick of sales. I'm sick of the mentality. I'm feeling burnt out. Idk if its just the pregnancy but its how I feel.

I started putting in applications to explore my options and got a phone interview scheduled at a bank. Am I wasting my time? Will a business even hire a woman 6 months pregnant? Is switching jobs irrational at this point? I feel so lost. It would be much better pay. I currently get $8/hour + commission and I'm sick of depending on commission to get by. I just want a steady income.

What do you think I should do?
