Well thanks for all your support and encouragement. With your advice, I did get the guts to ask my manager for 4 days a week. I wanted a Wednesday off, but they said it had to be a Monday or Friday (as these days are quieter than Wednesdays) and also I don't start my part time until Week 31 (so I will have 4 weeks of 4 days a week). I'm happy with that - better than nothing! Most days are still a struggle and I have decided that I'm not very good at being pregnant! I've been having a nap at lunch time to help me through too.

Thanks again for your support - I was very nervous about asking!
