Personally I would wait Penguin and talk to the midwife about it, but if you're really worried, maybe give it a go?
My positivity last about four days, but yesterday I got a whole load of appointments in the post for the consultant, with a note from the midwife saying that I won't be seeing her at all because of my bmi and history. My glucose levels indicated a raised risk of gd so I have the proper two hour gtt on 9th July as well as a 2 hour appointment with the consultant. I feel awful, like I've let this baby down before I've even had it. That it was selfish of me to get pregnant when I'm so massively obese (size 16, imagine). I'm going to end up having a giant baby that will get diabetes and a highly medicalised birth with no choices.
I can't help thinking that sending all this stuff through and then saying we'll see you in four weeks, with absolutely no guidance about what I can do to help myself or the baby in the meantime is fucking lame.
Bollocks, I've made myself cry now.
On the subject of maternity leave, I'm planning on taking a year and won't be back in the office until January 2016, thanks to the 30 days holiday I'll accrue during 2015 when I'm off. Aiming to go off on 21st November, unless all of the above indicate an early arrival. Saving a bit of this years annual leave to add onto the front so that I'll get paid for longer. I get 18 weeks on full pay, 21 on SMP. We are saving like mad to cover the last three months unpaid.
