I had and have an anterior placenta and last time around I didn't notice any movements until around 23 weeks, so it's perfectly normal to not feel anything yet! This time around I've noticed a few tiny flutters, but that's mostly because I know what I'm feeling for now. I'd have just ignored them last time around as gas bubbles or muscle twitches.
I had a homebirth last time and I'm planning on the same again this time around. Different home, but actually means we'll have more room and that the birthing pool doesn't need to go in the conservatory! I've already booked my birth pool. I have a feeling it's going to be tricky to prevent DD from using it as her personal swimming pool, however!
DD was a bit early at 37+3, but not so early that it was a problem. Hopefully this LO will arrive at around the same sort of time. I'll feel rather annoyed if they stick around until 42 weeks and have to be evicted - I'll have spent an entire extra month pregnant over last time around! Will mean I'm less likely to avoid the stretchmarks as well...
Got our scan on Saturday too, I can't wait to find out!
I was talking with DH about it last night and we don't really mind whether it's a boy or another girl. If anything, we're leant slightly towards hoping for another girl as we can reuse more clothes. [stingy]
Might also even up against the lots of lovely baby boys that seem to be due on this thread! 
Saw my MW on Monday for my 16 week appointment and got to hear the HB which was lovely. However she doesn't want to see me again now until 28 weeks!
Given how short my appointments have been, I may have seen a MW for less than an hour in total before I give birth this time around.
