Congratulations, tally! Great to hear it all went well, and Imogen is here safe and sound.
Me and you up next boom (and katatonic too). No sign of action here, though, and I'm not due until the 23rd, so probably a little while to wait yet. My little one is head down and engaged, so hopefully all will happen naturally. Just trying to be patient now, which is getting harder now I look like I have a beach-ball up my jumper!
Re: small bumps, I don't think there's anything much to worry about - everyone shows differently, and so much of mine has appeared in the last 5-6 weeks. In fact, in a highly uncharacteristic move, I've been weighing myself all the way through (I didn't even own bathroom scales before getting PG) and I've put on 3 kg in the last month and probably only a kilo of that is icecream. 
Did so little yesterday that I made myself feel quite down. So with the sun out today, I'm going to see if I can plant some sweet pea plants out. Not sure what position I'm going to need just to reach the ground, but it could get interesting! Just hope the neighbours aren't watching...
