I plan on leaving work around 18 weeks...or just going down to one day a week. I've been having problems with workmates though...am 7wks PG and had to tell work right away as I am a vet nurse and 80% of what I do can be dangerous, but they have tried to find work for me that I can do, but I find the other nurses a bit put out because it means they have to do a lot more work than before as our boss will not hire someone else...so I have gone down to 25 hours as soon as I could (next week! ). But work has made being PG for the first time not entirely joyful...
