Hi RatherUninspired Sorry about delay in replying. Have suffered had the great in-law invasion.
I too have developed a sweet-tooth that has hitherto been dormant. But I think it fell short of a craving -had to do a GTT which came back negative but did kick me into shape a bit.
I must say I don't hate pregnancy, but I do understand where you are coming from. I think I am fortunate in that most of my female friends do have babies, and one of them certainly did hate pregnancy so I haven't felt the pressure to love it. However, it certainly becomes annoying when you say "I'm really tired" and are constantly met with "Well, just you wait till the baby is here" - YES, but I'LL HAVE A F*ING BABY. 
Try not to worry, I think being in the latter stages of pregnancy is also a huge anxiety hike (as I have also found every scan to date). It certainly is for me. I'm currently wondering about what I actually do with a baby, and also thinking that maybe this is something I should have researched/ learned beforehand, and that i'm potentially a terrible mother for not doing so. Then I remember that actually I am quite a capable (comparatively to some other people at any rate) human being, and have no reason to think that I will suddenly be worse at being a mum than I have been at anything else. I also know that I have a lot of love in me to give,and if I love this baby then that is a pretty good place to start.
I'm sorry that I can't speak from previous experience with this being my first, but I do understand where you are coming from. I am sure you will be a wonderful mum
- and don't forget that a little human that you live with is a lot different to some unknown entity that is inside you, heavy, crampy, winds you every now and then and means that you can't "just lie down" without contemplating the least uncomfortable way in which to do so. Although there will be feeds and nappies to navigate.
Good luck for the birth- when are you due?? Please keep in touch on here. I'm so sorry you are having a bit of a hard time with it, but it is kind of nice to know i'm not the only one. So thank you for that 
DH update- Turns out it needed an antenatal class for him to snap into gear. Not only am I able to delegate activities (although I still hate doing so), but when all his family came round he was definitely on my side in the face of all kinds of "advice" being offered from in-laws. So today my hormones deem that he is a good guy and so I won't have to kill him. But thanks for your eyes? ears the other day.
