Not financially ready for baby #3

I don’t know what to do. We are already struggling with our debts and paying the bills. I was on the Nuva ring using it correctly and replacing it correctly and I wasn’t on an antibiotic. I don’t know how this happened. We are not ready for a 3rd kid but we want this baby and don’t believe in abortion. I know we will have to figure it out but I just don’t know what to do 😞. I’m going to be let go from my job as it is a very demanding job and I will not be able to do it pregnant though they will take me back after the pregnancy in a heartbeat! But I don’t know what I’m going to do during pregnancy and a few months after birth. I’ve worked pregnant in my first pregnancy but as soon as I got close to my due date I was fired for “not doing my job correctly” which is untrue as I was doing it perfectly 🙄. And with my second pregnancy when I went out to get a job I was overlooked for someone more “qualified” (not pregnant 🙄). We were only going to stay at one child until we got our lives together, then my birth control (daily pills) failed with my second. We figured it out then but it was easier. Now if I lose my job we are going to crash and burn 😭. I’m currently looking and applying but from experience no one hires a pregnant woman. Do I lie and say I’m not pregnant? I can only do that for so long. This my third so I’m going to start showing quick. My current job is going to keep for a little while but I can only do so little for them now so they can’t keep me on for long. I guess what I’m trying to ask is there any jobs that a pregnant woman can get easily? I’ve never tried online jobs, are they worth it? I have good WiFi and a computer.
