OK, I've fished mine out.
1. Are you sure it's an "r" on PrG. It could be P1G, meaning pregnancy - 1 (you are currently pregnant), gravida - 0 (no live births). So the P is for haow many times you have been pregnant and the G stands for how many live babies you have delivered

2. I can't find stat (I presume it means status too) on mine anywhere....are you under shared care? Could it mean midwife/obstetrician??
