AUSTRALIANS HELP PLEASE.

So, I'm 11 weeks pregnant and I'm extremely sick. I can barely stand up. I tried going back to work yesterday and only got 3 hours in before I had to go home. It's absolutely killing me and I'm not going to be able to pay my rent this month. So my question is, will centerlink help me for this reason? Or will they make me look for a job or "work for the dole" in order to get any payments? I have a full time retail management job and I'm on my feet for 10 hours a day and I just can't do it at the moment. Please help me.
