What would you do

I am a brand new nursing school graduate. I had an interview for a new grad position back in July. I found out I was 5 weeks pregnant last week and this week I found out I most likely got the position. I won’t be able to start until October and after boards. By then I will be around 14 weeks. I’ve never been in this position to tell an employer I’m pregnant at the beginning. I know I dont Legally have to until I’m ready. I just don’t want to get the scoffing or looks that may proceed the news. I want this career more than anything, but apparently a baby was God’s idea of a graduation present rather than a new car. I am extremely happy to be expecting and excited, but I also feel like I’m in a bit of a pickle.
