If I was in your shoes, I'm not sure I could stick it out until well into next year if I hated my job. It's an awful feeling to be miserable at work.
I'm also not sure I could go through with taking on a new full time role, then later down the track dropping the bomb on the employer that I was pregnant. Although it's perfectly legal not to disclose pregnancy, I would worry that my employer would judge me as being dishonest. Of course you could be upfront about it, but there would be a lot of employers who would consider it unfavorable to employ a pregnant woman.
What about temp work? Do temp/contract roles come up in your industry?
