From the WG side the mother to be she is taking a risk with a dodgy punter hurting her or being rough and seeing strangers does come with risk and that is ok if she is making that choice for herself but the kid inside her don't have a choice.
If a wg has worked a while and then just got knocked up surely she could afford to take some time out rather then working through the whole pregnancy but some I think actually want to make money just off being pregnant to me they are selfish advertising come fuck me with my bump.
Pregnant women take risks all the time. Driving, what if they have a car accident? Crossing the road, what if they get run over? Going out in winter, what if they get a cold or pneumonia? Having protected sex while pregnant can be perfectly safe.
Pregnant or not, rent, bills and living expenses still need to be paid right? Generalising that all pregnant WG's are selfish and evil human beings is an interesting viewpoint to take. If it were me, and I was pregnant with the knowledge that post birth, I would not be able to work for some time, and had taken the correct medical advice that having safe sex will not harm my baby, I would be inclined to cash in while I still had something that resembles a vagina.
Then I'd take a few months off, maybe even a year to take care of my little one, without the worry about who is going to pay the rent during that period.
There is always more than one side to a story I guess
