Millie - I agree with the others. My friend who's a midwife, didn't feel any movement til 22 weeks and I thought she might know what to look for but it doesn't work like that! You've probably felt it and not realised what it is. It's something that becomes easier to detect the more you have. Sure everything will be fine.
Re: Sleeping, my sleeping is totally crap at the moment,I mean, I've always suffered from insomnia anyway, but at the moment I think my hormones are starting to keep me awake (always did the week before my period was due so I know hormones can do that) also, very weirdly, I often get like this when there is a change of season, and also in the run up to my birthday. (Certainly not because of excitement anymore!!) Of course, DD2 waking up 3 times a night to find her dummy really doesn't help as then it takes me an age to get back to sleep. Anyhoo, I recommend those body pillows, I got one with my first pregnancy and am about to get it out again.
Beats cuddling up to your snoring, farting DH!
