Getting a second job at 23 weeks pregnant...

Just looking for some advice or opinions, right now i work front desk at a chiropractor's office and it's getting hard for us to make ends meet while also saving up for time i have to take off after the baby comes. My current job offers no maternity leave, it's a small business so basically my boss is just holding my job for me until i feel ready to come back, but i'm not getting any paid time off whatsoever. I know this late into my pregnancy i probably won't get any benefits at another job if i start now, but i really need the extra money. I can only work saturdays and sundays because of my other job. What kind of job should i look for and would i have any luck getting hired?
