Am really feeling the extra weight I'm carrying, everything is getting hard, even simple things really tire me out! And when I saw the midwife yesterday I very nearly fainted, I have no idea why. Feeling stressed because I've got a couple of rooms to decorate (our room, room I'm moving my dressing table into and touching up paint in Nursery) and my husband is being frustratingly slow at getting rid of clutter so that we can do this. I can't do it as it involves lifting but he doesn't seem to understand I want it doing so I can relax, it's really stressing me out. Hate to be so grumpy but feeling slightly powerless.
