Those pregnant photos are most likely fakes - she looks way too old in those photos and the photos look too “new”...like they were making the current Michelle Obama pregnant at her present age.
But plenty of legitimate photos of her as an infant with her family, as a young little girl, and yearbook photos from her school days, etc. very much exist. She was never named Michael and never presented as a boy/man who later “transitioned” - total obvious fiction. If she is actually not a “she”, then that was something her parents had to have started starting from the time she was born, but she was also never named Michael - always Michelle...so it still falls apart.
Thank you. I did go to the snopes link posted which says the same. But, like many have noted in the thread, it is not unusual that there aren’t public photos of a private woman pregnant during the 80s. For comparison I googled Melania and there are tons and tons of photos showing her pregnant with Barron. But that’s to be expected since she was married to a famous reality TV star and attended many public events with paparazzi and media coverage.
