Afternoon ladies, welcome to newbies. Defo a baby boom year! 
Orange the leadership at your school sound so unprofessional, the fact you are receiving emails about your performance on a Sunday is enough imo to count at harassment. I second what bree said, not the norm at all from my experience and teacher friends- but unfortunately you're not the first (or second) person I've come across that's had this sort of nonsense thrown at them. People's performance doesn't plummet overnight, or in a single term. And any employer that feels it has should be able to back that up with facts and put support in place. Pushing people out is vile. I would go to the union even if its just for some legal advice that's specific to the teaching profession.
In other news, bump is feelig heavy at the bottom and wriggling baby is sometimes uncomfortable- feels like he/she likes to poke their bottom out of my stomach and fall asleep on my bladder. I still smile when I feel it though, just worried about how uncomfortable I will be by oct 
Can't remember who said 18 weeks is a good milestone but I agree, my notes say labour ward if probs after this point (scary but a milestone nonetheless)
Falcon, hope you're out in time for a nice Sunday dinner with a new lease of life, must be annoying to keep being put off.
Ooh and thanks for the feedback on Raphael, am most excited!!
