Padme has a gigantic penthouse apartment, multiple ships, and a sqaud of literal servants, she can get herself to the fucking ob-gyn good lord. Anakin is off fighting a war, not keeping her barefoot and pregnant and hiding the car keys for fuck’s sake
Like, if anything is to blame, it’s probably Padme’s misguided romanticism convincing her that she can totally hide this baby if she just doesn’t consult any medical professionals about it. I love her, but she operates on sheer audacity and honest belief and sometimes that backfires. See also, her heartbreak leading to her death, because that’s exactly the sort of operatic stunt Padme “Body Doubles, Questionable Politics, and a Secret Husband” Amidala would pull. Let her have her fatal flaws and personal agency, people.
(That and the writing is at fault, but that’s another matter.)
