Thank you for your opinions/advice everyone. :)
Have just come back from midwife appointment and had some blood tests they wanted done, as well as my anti-d injection. Both were prickly but just fine. I managed to gather the courage to ask her lots of questions today, which I'm chuffed about. Asked why I needed to see a consultant half an hour away when the midwife at my local surgery could do the same things, she said with my history of being vegan and an eating disorder I need to see a consultant throughout my pregnancies. Also asked about a possible extra scan, and she said she'll get back to me on that one and check again at around 35 weeks. I'll probably be put on prescribed iron tablets which is good as then I can get the dosage/mg right!
Felt and measured baby at appointment, I'm 28 weeks exactly today, and she's exactly 28 centimeters! So glad as it clears my fear of LO being big. Midwife said she was very wriggly and could feel her, so that was lovely. :)
Talked to her about the itchiness, and she's prescribed me some cream which I'll be picking up tomorrow.
Our benefits have been sorted out now thankfully and we've changed so DP is on Carer's Allowance and claiming couple's Income Support now. I'm so relieved and this will lift a lot of the stress for me, as I can relax more about affording to buy baby stuff now.
Does anyone know any shops that do (inexpensive, not more than £25!) airy/light/comfortable trousers? I rather like some pajama bottoms as the fabric is thin and I can wear it under a dress for extra comfort, but they're getting a bit small! Mind you I need enormous sizes simply because bump is huge. So shop would need to have plus sizes. 
Sorry for colossal post!
