Nervous

So i’ll be done with school on Wednesday as a Medical Assistant. Tomorrow I have an interview with my externship site, and I’m really nervous!! I don’t know what to wear !!! Originally I was planning on going to my interview with scrubs because my career advisor from school said that I can either wear scrubs or professional attire. So I chose to go with scrubs , because I’m 7 months pregnant and I wanted to be comfortable. I started researching on what to wear as a Medical Assistant going to an interview and it all said to go looking professional! I’m trying to make a good first impression, so now I’m thinking about not taking scrubs. Not to mention, I don’t even have no professional looking clothes especially now since my stomach is growing and anything hardly fits now !!!! What do you think would be best ?! My interview is at 3:15 pm tomorrow so I have time to go buy stuff .
