OK. This term confuses me. I’m reading an article about a barmaid who was fired for being pregnant and the article said:

Barmaid who fell pregnant told to leave before becoming ‘fat and wobbly’

Bar manager who fell unexpectedly pregnant was told by bosses she would have to go before she became ‘fat and wobbly’

What on earth could that mean? Fell? Did she fall into a bed where a man was unexpectedly lying? I’m sure it means unexpectedly pregnant but they make it like it’s catching a disease in which they had no part.
