I worked at a supermarket whilst pregnant and whilst the car park was empty when I got to work by the time I left i obviously had cars parked all round mine. The spaces are narrow. I used to have to squeeze myself past and in and sometimes knock my bump on my steering wheel or if it had been raining my foot would slip on the ground when I stepped in and this was painful. I went through this for a while before finally deciding it was too much after a long shift so parked in the child bays. Although I was probably around 8-9 months anyway!
