Inconsiderate commuter

Currently I am in week 25 and my tummy is significantly obvious to be identify as pregnant. Honestly, I am not self entitled expecting people to give up their seat in mrt to me. (In fact I prefer to stand instead lah) But i get very annoyed when I am being squeeze into crowded train and happen to be standing infront of the reserved seat. This auntie (around mid 40) who was sitting on the reserve seat got the cheek to pretend never notice me and just continue to watch her video! Is it just me being sensitive or people are just so inconsiderate?? Anyone encounter same situation as me?
