Nannying at 30 weeks pregnant?

My family really needs extra income. I don't do anything all day and its starting to take a toll on me. I was looking into nannying since I've been caring for babies and children since I was 10. The only issues I'm having is that I'm 30 weeks pregnant and I feel like nobody is going to want to hire me for such a short amount of time.

Should I at least try or just wait until after my son is born? The extra income would help so much and I wish I would've thought of nannying sooner, but I didn't... Also, I'm not sure if its appropriate to ask if I could bring my son with me since I'm going to be caring for their children anyway. I don't have to bring him, but it would be a lot easier since I'm going to be breastfeeding.

Edit: Thank you for the suggestion, Veronica. :) Unfortunately in my home isn't an option for me. My male partner and our roommate game and scream all day which isn't a good environment for children. Also we'll have pets and some parents, especially here don't like that.
