Cobie Smulders had a couple of episodes in How I Met Your Mother where she was pregnant, and during her 2nd pregnancy she did a movie called Unexpected https://www.imdb.com/title/tt4145304/

May Lindstrom very briefly in Her from 2013.

(March 6, 2020, 9:08 am)wsxb I know many movies with real pregnant actresses.  The list is the result of me hunting those info for more than 9 months.
I always think about that if I can create a new thread for these movies.

The following list shows all movies I found so far.  Some may already have been mentioned in other replies.

• Autoerotic (2010) - Kris Swanberg, with her 1st child inside
  
• Banat (2015) - Elena Ranonicich
  
• If They Tell You I Fell (1989) - Victoria Abril, 6 months pregnant
  
• L'amateur (1996) - an unlisted actress, at 05:31 - 05:45
  
• Los violadores del amanecer (1978) - Alicia Orozco, as a member of the evil rapist squad
  
• Love Comes Quietly (1973) (a.k.a Angela) - Barbara Hershey
  
• Olmo and the Seagull (2015) - Olivia Corsini, as the character counterpart of herself
  
• Otesánek (2000) (a.k.a Little Otik) - an unlisted actress, as a patient without her face shown
  
• Neon Bull (2015) (a.k.a Boi Neon) - Samya de Lavor, 8 months pregnant
  
• The Paperboy (2012) - Shannon Trosclair, not related to the main plot
  
• Policeman (2011) (a.k.a Ha-shoter) - Meital Barda, with her 2nd child inside
  
• Prevenge (2016) - Alice Lowe, 8 months pregnant
  
• Revenge of the Cheerleaders (1976) - Cheryl Smith
  
• Story of a Love Story (1973) - Dominique Sanda, pregnant in the scene before all other scenes filmed
  
• Sugar Town (1999) - Lucinda Jenney
  

Some TV shows also feature such kind of characters.

• Girls Season 4 - Gaby Hoffmann
  
• The L Word Season 2 - Laurel Holloman
  

There is one more movie with a real pregnant body double of a non-pregnant actress

• Plonger (2017) - María Valverde's body double
  

This one is something I can't tell if the belly is real or fake, her own or belonging to a body double.
I tried but failed to find solid evidence on the web. Any more information is appreciated.

• Diane Has the Right Shape (2017) - Clotilde Hesme
  • Clotilde Hesme was very pregnant in Paris at Feb 1, 2016 (Youtube)
    
  • The filming started shortly after Jul 4, 2016

Oh, I know Her/her as well, just forgot to add that.
Aside from the short scene as a pornstar in the film, she has some nude pictures on the web.

I've created a thread on Open Discussions with a list of such movies. Please let me know if there are more movie/show names to add.
