The women sit outside - you can just about see them lined up on the ground floor of this photo, between about 30 and 65 women come each Tuesday when I am there. They also have antenatal clinic one other day and a couple of booking clinics each week.
The women come inside and get weighed, their urine and blood pressure checked. They then get called back one at a time for their checks. There tends to be two midwives working here, there are two curtained off areas with a couch , although when ward or labour room midwives are not busy they also help out and use any free beds for antenatal checks.
This is one of the clinic rooms. Each has a couch, a trolley with some medicines laid out and basic equipment such as tape measures and fetal stethoscopes. One busy day I did end up delivering a baby in this small space here too :-)
