i would imagine if you have enough annual leave days, it should be ok, like tk1999 said, if they know you wont be there on wednesdays, they could get someone else in and work would get done!

i can relate to the morning sickness thing. i finished up work at about 27 weeks (i was only casual in a take away shop) because i just couldnt cope. we are now so horribly broke, becasue i thought i would last longer at work.

it cant hurt to try. i would say speak to your doc, if you have a supporting letter, it might help your case!

GL!
