Interview while 30 weeks pregnant

Becca • ✨✨Mother of 2 ✨✨
Just recently I got a phone interview for a new job I am very excited since my current work situation causes my stress level to go up and I get physically I'll and anxious just thinking about my job. 
I'm wondering should I tell the interviewer I am pregnant since it is just a phone interview or should I wait to see if I get a face to face interview.
