@Milknosugar1 omg are we living parallel lives? I went to Dunelm as well today for curtains before my Lego adventure!
This is because although we have blackout curtains in our bedroom they're a tiny bit too narrow and there's a streetlight outside that has recently been keeping me awake with the glow round the window.
I found the right length and width after much faffing and accidentally jostling a very tiny elderly lady, got all the way to the front of the till before realising I had picked up pencil pleat ones and not the ones with the eyelets and had to make an embarrassing shuffle all the way back to the curtain section where I dislodged a large pile of them trying to pull the right ones out.
I did get a free cake and hot drink voucher but I don't think I can show my face there again!
Maybe Dunelm should be added to the list of things pregnant women aren't meant to do 
Based on all this, you're probably better just getting new windows. Or a new house. Or maybe doing away with windows? I'm sure the "dark box" trend will be along at some point to replace "everything is grey"...
I know what you mean about feeling like a halfwitted zombie. Even when I'm feeling a little better it's like I'm in a fog of being mildly confused. OH has been good too, but he's been on call for work loads lately and when he gets home I think the cats and I are freaking him out. I'm usually very independent but lately it's been like "Hurrah! THANK GOD YOU'RE HOME!" and since the cats are now glued to me at all times he get gets a strange little welcoming party.
I feel like shit for complaining as well, especially as have told so few real life people. My boss has been really nice but she had a very traumatic time with her youngest (thankfully now a healthy 2yr old!) so I don't want to whinge too much to her.
