Lauraloo It could be pain from the muscles having to do extra work to counteract the SPD. I had this last time and a few twinges in my knee this. Always best to get it checked out though. Be kind to yourself, if you need to take time off take it, SPD is a killer.
Bubbless To measure your bump lie back a bit and put the bottom of the tape measure on your pubic bone and run it up your tummy til you get to the top of your uterus. Have a prod around to feel it with your fingers, it should feel quite firm and you can feel it going back towards your insides IYSWIM, try about an inch or 2 above your belly button at this stage. Then press the tape back until you can't go any further, with out hurting yourself, don't press too hard 
eggs what a great day, lucky you.
gils My Dh is being fab too, I haven't cooked a meal all weekend. I'm very lucky, he works really long hours, but does a lot for us all at the weekend.
Bump size, it's small talk for pregnant women. It's a replacement for talking about the weather, but obviously a lot more personal. A swift it's just the right size thanks, usually does the trick 
I've been baby shopping!!!!!!! I was very happy, the ds's not so much, but they did get to spend their money box money on lego and are now happily building away, so that ok, right? I bought; nappies, wipes and nappy sacks, not very exciting, but also this and a fab hat with a cow on and they were 30% off too, so also saved some money
I feel like I'm finally getting started. I must give my knitting some attention now. With all the cleaning and sorting, it has been neglected somewhat.
Hope everyone is well.
