Thanks, Woowa. I think it'll be ok. It's just all a bit much at the moment. We'll find a way to make it work. The house will be ok to start with, I think. It's only 2 beds, but I have a front living room which can be a temporary bedroom for a while when the little one is ready to move into their own room. The other two boys aren't with us all the time. DP's DS is only going to be with us for a couple of nights a week (his mother permitting - but that's another hurdle to overcome) and I have a shared custody arrangement with my ex, so I have my DS for half of each week and every other weekend.
In the long run we can convert the loft, but that will have to wait a while.
My initial reaction when I found out was that I couldn't have the baby - that it's just impossible, but I couldn't go through with a termination. It's not that I'm against it, but I just (irrationally probably) couldn't face it. I always wanted more children, but assumed I never would after the last time. I want the baby, so I'll just have to make the rest of it work somehow.
Good luck with your speed awareness course. I'm sure it'll be fascinating! Better 4 hours of boredom than points though.
I've never heard of a veg aversion. Last time I had a processed food aversion and couldn't scrape leftovers into the bin without puking. I haven't had any aversions this time.
Also, I went to the midwife on Thursday at 16+1 and they listened for the heartbeat and it was loud and clear, so ask on Tuesday and they'll probably do it for you. It's weird, but I hadn't felt any movements before that, but now I can feel all sorts of wriggling. He/She's quite squirmy! Are you going to find out the sex?
