This is what I do, and it wins for all sorts of reasons, not just the avoidance of mistaking flab for a foetus. If you are doing this, the likelihood is that there is someone more in need of a seat than you, and possibly for invisible reasons (e.g. carrying a minor leg injury, first trimester of pregnancy, or just tired). Some people in a certain age range (mid-late 60s) may be grateful for a seat, but don't want to think of themselves as old enough to warrant being offered a seat. The person you think you are getting up for may not want to sit. When my wife was pregnant, she was inundated with offers of seats. She often refused, because on shorter journeys, the effort involved in sitting down and standing up again was greater than that of just standing all the way.
