Working while pregnant- vet nurse

I’m 11 weeks and 4 days, I’m only 20 and I have studied to be a vet nurse and worked as one for 2 1/2 years. I left a year ago as I moved. I took my new pup in to get vaccinated at my new local clinic and mentioned I was a vet nurse and they told me to bring a resume in (before I got pregnant) I got a call today saying that they want me to do a few trial days next week and go casual then full time. It’s my dream job and I’m so shattered as I don’t think they will take me on since I’m pregnant. It’s a risky job all the drugs, large animals, aggressive animals and on your feet all day kind of job I just don’t think they will allow it. I’m going to tell them when I go in for a trail and I’m assuming they won’t take me on after that :( any opinions? :(
