Finding a job while pregnant

Sooo I was working before, actually I was pregnant back in February had an MC and kept on working and got pregnant right after. Since I suffered from recurrent MC my doctor said I am high risk and my first 3 months of pregnancy were critical that I should really take care of myself. So I decided to leave work the first 3 month since it was a very high stress, high demand job. I thought I was doing what is best. But now I’m in the beginning of my second trimester and I am having NO LUCK with a job. I’ve had more than a handful of interviews and nothing. Is it harder to find a job while pregnant? I try not to disclose that I am pregnant but I am kinda showing already I’m a slim girl and I’m all baby. So it’s obvious. I don’t know what to do I’m so frustrated with being home and I want to start putting money to the side for the baby and myself since me and the father are most likely separating. I just want to be prepared. Has this happened to anyone else? How do I go about this? What can I do? Please any advice
